Certainly feels like the model is being way too aggressive hedging against the convention bounce, and is effectively giving Trump a bounce instead.

Expand full comment

Yep. I was saying weeks ago that Nate is likely going to be over-doing the bounce adjustment because Harris was already on a roll. A DNC bounce was already going to be muted, and then you add that RFK kind of stole the headlines right after the DNC (obviously intentionally)

Also the polls that show Trump ahead in PA are mostly low quality.

I have a feeling that the Trump campaign and the MSM are going to specifically point to Nate’s model to “formally declare” that the DNC was a dud and produced no bounce, that Harris has lost all her steam and now Trump has the “momentum”. The problem is this narrative has a psychological impact on undecided voters..

Trump would have made a claim like that regardless of what any model says.

I don't think voters are paying that much attention to media pontificating about who has the "momentum". Especially if it's based on a shift of a few points in a forecast hosted in a Substack newsletter that primarily nerds read.

What really might happen is that undecided voters tune out from the race for a few weeks until something happens in it again. Such as a first Harris-Trump debate.

I guess. Insofar as my personal opinion and words online have any impact, I don't see much difference.

The only thing I feel is relevant from 2016 is that now I'm prepared that, regardless of what I believe, what I think the polls say, what I think other people *should* believe, Trump may yet win. And that much I have accepted as fact. Trump may win. It's not over until the fat bastard sings.

Considering the post DNC Emerson College poll is one point higher for Harris than their previous poll in August (showing Trump +1), and the model is weighing it heavily it seems like it's too hard of an overcorrection.

Agree. But deep breaths — as model problems go, this one will be gone in a couple weeks. Would love to know the nowcast though.

Expand full comment

538 has fixed its model to be 80 plus percent based on polls and not so fundamentals focused. They show Harris leading by 3.6% similar to Nate. And a 59% probability of winning. Her record for Nate's model is 57% probability of winning with a 3.1% popular vote lead. Until Nate's DNC adjustment period ends in 2 weeks I'm ignoring his model and assuming 538 is a nowcast for if she holds her 3.5% lead.

I wouldn’t trust anything they say until it’s been at least a few election cycles and their model has been proven to have some actual predictive value. Pretty clear that site is beyond dysfunctional right now.

Expand full comment

538 has “fixed” its model? Come on. 538 had Biden at 50% in June. Their model is a joke.

Expand full comment

I don't think that's far off from the truth, as in I don't think it's so significantly off from Nate's model that you can credibility claim to believe one and not the other based on this fact alone. There's still 2 months until the election, and probabilities are not destiny. A model showing Biden at 50% in June is not de facto bogus.

If you're saying this based purely on your impression that people *shouldn't* have been supporting Biden, then I'll just counter with there's a much larger expectation popular expectation that people shouldn't be supporting Trump, so the fact that that support is measured in a model isn't evidence against that model.

I definitely trust Nate's approach more than most of the public election models, but that's as much about his commentary about where the model may be falling down as the model itself.

Aug 29·edited Aug 29

A huge bonus with Nate’s model is that he’s open about what the bounce target is. And so you can see while it’s in line with several decade average, it’s not inline with the last 3 cycles which we know is a very different environment vs 2008 & before.

Frankly I very much expected this, although RFK Jr wrinkle probably exasperated it a bit.

Expand full comment

"exacerbated".

This is becoming a problem. "Exasperated" sits between "irritated" and outright "angry".

Expand full comment

????

Why did you switch words? You seem very confused

Expand full comment

Because "exasperated" makes no sense in that sentence. For one thing, it's an "intransitive" verb, denoting a state, not an action. It can take a person as a predicate nominative, as in "John exasperated me with his refusal to close the window."

It does not take a direct object which is a thing acted upon, in this case "the bounce target". "Exacerbated" literally means "made worse", which makes sense in that you were saying that RFK's withdrawal made identifying the size of Harris' convention bounce more difficult to discern.

Many people are making this error these days, because the words sound similar. They do mot mean the same thing at all.

Yes, it’s a typo.

That you still understood the meaning of, anyway. So calm tf down maybe?

Expand full comment

Yeah like, I hope I'm not doing some copium here but didn't Nate post just in this last week an infographic showing that Biden effectively got no DNC polling boost at all in 2020? Am I misremembering this?

Expand full comment

Even on a vibe level, it felt like there would be minimal bounce. Everyone had been fixated on Kamala since Biden dropped out...so what was the DNC really going to change?

Expand full comment

That’s what I think. I mean usually the candidate is fixed early in the primary. Then this person gets an initial bounce. Then a year goes by and the convention happens and gets ANOTHER bounce. Harris is having one big bounce, one could argue. I think it’s quite clear that her bounce can’t be as big as the one of any “normal” candidate.

Expand full comment

The narrow slice of reachable voters, especially the right-of-center or otherwise historically GOP or even 16/20 Trump viters that soured somewhat on Trump.

That reach to the center & disaffected GOP members, to allay the Red Scare stuff.

And I think we’re seeing that. Not in the differential but the absolute % climb.

Expand full comment

Yeah, IIRC, the assumed average included the +16 that Bill Clinton got in 1992!

Expand full comment

But Nate doesn’t take the average. Rather the model subtracts 2 points.

Expand full comment

And in that particular case that gigantic boost was, I have to assume, at least partly because it was essentially voters' introduction to him at large as the nominee, given Clinton was not locked in as the party frontrunner going in. Pretty much the more ceremonial version of what happened with Harris a month ago.

Expand full comment

He did. I think the explanation was that no-one cared because it was a virtual convention. It was certainly less exciting, but then again, isn't every convention just something that people watch on TV?

Expand full comment

The question I have is whether Harris got her bounce weeks ago due to the unusual circumstances surrounding her entry unto the race.

Given that typically “bounce” implies expectation of receding to some degree, a “bounce” that sticks & even increases over the weeks…is great news for John McCain?

Expand full comment

This seems pretty likely to me, though with how long it's been stretching I'm not sure I'd call it a bounce anymore (and obviously the simple probability numbers in Nate's model would suggest a sort of elongated bounce that's now fading but as other people here are saying, I think it's being pretty conservative right now). Nate's talked about working the model around Harris' late entry but I think there's maybe just some somewhat uncharted waters here he doesn't quite know how to fit the model around yet.

Expand full comment

I mean, all models are based on past history and obviously when you have significant changes the models become less relevant. The "art" in modeling is being deeply familiar with the problem space and knowing how to tweak your model/results to adapt to changing conditions.

Expand full comment

But changing the model/results according to "feelz" is also a problem. I know that Nate tries to change the model minimally during the election season. Agreed, that also leads to problems, when the landscape changes in ways not accounted for in the model. Damned if you do, damned if you don't.

Expand full comment

At this point I suspect that what really matters is the competency of the individual creating the model in terms of deciding what needs to change on the fly.

Expand full comment

Almost certainly yes. I think it's better to treat the "convention bounce" like she was the incumbent. I assume theres much less of an incumbent bounce when you already expect the nominee is decided.

It was already decided for her as if she had been the incumbent, she is literally the VP so she's at least incumbent adjacent, I have to guess the model behaves differently around the convention whether it's an incumbent or not, and if it doesn't it probably should.

Because the primary way to understand the post convention bump is not as a response to what happened at the convention, though that's a part of it. The primary way to understand the post convention bump is an alignment around the understating that this is the candidate, period.

Expand full comment

100% agree with this.

Expand full comment

Which is the opposite of what happened during the Republican convention. It'll come out in the wash.

Expand full comment

I might agree with this but say that it might not matter in this case, because it did feel like Kamala was also getting a honeymoon bounce since she entered so late after the "Joever" funereal vibes. So, it might be overaggressive, but it might be a wash considering that the honeymoon vibes could be wearing off soon.

Expand full comment

Or, it might mean that we're actually in the same place as a month after the convention, and the honeymoon period is already over and the polls are real.

At this point, hard to distinguish.

Expand full comment

If you feel a model i’d wrong, you should try to be more specific. You might be right, but until you explain your feelings, why should I credit them?

Expand full comment

I think many other responses have already done this. Harris effectively got the convention bounce from her entry into the race. The major question is, should we treat *her entry* as if it were the convention, in which case these polls would be treated with less skepticism at this point, or should we treat *all* of the time between her entry and the convention as if it were a long form democratic convention, and thus in some ways would be an entirely unprecedented scenario, which in modern politics at this level, it is.

Expand full comment

The Pennsylvania polling shift has the appearance of Simpson's Paradox*. The model is mostly weighting pollsters who have Trump ahead, but those pollsters are actually showing better results for Harris than they were the last time they polled. Curious what others think of this.

*If you take each pollster on its own, Harris is improving, but the composition of pollsters (and their weights) is changing in Trump's favor.

Expand full comment

Should we expect the house effect adjustment to address this completely? I'd think the distribution of pollsters over time would be stationary -- no particular reason, at least not one that can be modeled easily*, to expect pollsters with particular house effects to go into the field at particular times.

* Certainly if it's adversarial, with pollsters timing their releases to influence the average, that's a whole 'nother can of worms.

Expand full comment

Over time yes, but in the day to day snapshot, the model assigns much higher weight to the most recent handful of polls, which could create some noise.

Right now in PA, the most highly weighted poll is one that shows an even race, but that pollster’s most recent poll was a +1 advantage for Trump.

The third most highly weighted poll shows a slight margin for Trump, but that pollster’s most recent poll before was +7.

Also of note, the convention bounce adjustment is subtracting ~2 points from Harris for polls that happen during the DNC. That is probably more important than what I’m going on about.

Expand full comment

Though even if changes in the mix of pollsters don't contribute a mean shift, I wonder if they should inflate the variance. Does the model condition on the timing of polls by particular pollsters? Or are they random and resampled somehow?

Expand full comment
Aug 29·edited Aug 29

Yeah Emerson is +0 in PA now, but was +2 Trump for Aug 13-14. So actually an improvement. I wonder if the convention bump is really what is causing this discrepancy though? IIRC the model does not try to calculate a "bias" or anything like that in polls, so even improvement in one particular poll matters less than just the most recent available polls.

Expand full comment

I think it's better to not focus to much on the convention bounce. My gut says that the primary motivator of the convention bounce is the consolidation of support behind the party nominee, and the universal understanding and acceptance that *this* is the nominee, no matter what. If that's the case, that would have been the situation for Harris the moment she entered the race, not at the end of the convention.

In which case, either the convention bounce happened already, and has passed, or we need to think of the *entire window* between her entry to the race and end of the convention as if it were "the convention", which means we need to treat her *earlier* polls as if they were convention polls, too. Or, probably more accurately, it means we need to treat this like a unique situation that a model is gonna have a real hard time accounting for until after it's already happened.

Either way, all we're trying to figure out is how accurate this particular model actually is. We'll figure out in a couple of weeks, when the model thinks we're in the post convention period, how weird or not weird the reversion to the mean looks. I expect the reversion to be low to non existent, and the model to show improved chances for Harris as a result. But we'll see.

Expand full comment

I was with you until that last sentence. Let it go. There was a risk that if she chose Shapiro it would have been spun as 'oh, she's trying to win PA', i.e. that she makes her decisions only with regard to short term political calculations and therefore we shouldn't trust her. Do we really think the media wouldn't have done that, given that they all want Trump, because they think constant crisis and fear is good, even necessary at this point, for their business model? Years of fascism and the elimination of all of our freedoms just to sell more papers. Talk about short term calculations.

Expand full comment

I agree with "let it go", but for different reasons. Shapiro had a bit of baggage dragging around in the local PA media. Some of it maybe sorta could have been damaging? Let's say Harris chose him, and those stories surfaced. Would a two or three week media cycle about Shapiro with salacious whiffs have overshadowed the Democrat convention of "joy"? Maybe. Add to that perhaps (maybe) a lot MORE Gaza protesters (not an endorsement, just a prediction)? That convention could have gone off the rails and thrown the vibes out the window. Walz meanwhile has proven to be a solid choice, with his military service attacks petering out, and his Midwest charisma on constant display. I just don't think there was some magic bullet that would have delivered PA to Harris, and I'm definitely skepitcal that Shapiro would have been a net positive, given his local troubles.

Expand full comment

All good points. What I read at the time was that Walz wanted to be fully a team player, while Shapiro had too many of his own ambitions and agendas. If so that's a sound reason for making the choice she did imo.

Think all nate is saying is that PA is likely a tipping point state and Shapiro would have increased Harris' chance of winning the state -- be it incrementally compared to Walz.

What alternate universe are you inhabiting? The majority of the MSM themselves admit that they are Dems and personally dislike Trump intensely.

Expand full comment

And I was likewise with you until the end. One might argue that media owners want Trump (though I'd disagree even there, aside from obvious cases like Fox), but certainly most of the actual writers and editors producing copy for the msm would prefer Trump lose.

Expand full comment

I dunno. People do stuff against their own long term interests all the time. And in terms of short term benefits, whatever else you might say about him, Trump drives ratings. He's sort of like an idiot Howard Stern. TV journalism at least, has become entertainment in a reality TV sort of way. I could definitely see CNN et al "overcorrecting" with Harris criticism, Trump winning, and not crying about it after. Trump already enjoys a scenario where the MSM tries to present his statements and interviews as WAY MORE coherent than they actually. It's an exhausting asymmetry. If Harris said ANY ONE THING that Trump did, the MSM would torpedo her campaign

Expand full comment

It is hard to know what the owners truly want in their hearts, but I think that there is a fair perception that Trump is good for media because he drives engagement. I have certainly noticed that the nytimes aggressively fact checks the Harris campaign in a way that they do not for Trump (by contrast, I find AP news much more reasonable). Whether or not this reflects actual pro-Trump bias I can't say, but I do think that the _effect_ is pro Trump.

Expand full comment

The fact-checking may have more to do with novelty. When the Harris campaign says something that isn't true, it's news. When the Trump campaign says something that isn't true, it's a day of the week ending in Y.

Expand full comment

On the other hand though, journalists are smart, knowledgeable people, who broadly realize that Trump is unfit to be president. So yes, they're going to follow their instincts and write what gets attention to some extent. But at the same time, they broadly want Trump to lose, because they're also Americans and human beings who don't want bad things to happen. I think it's easy for those of us who agree with Trump's unfitness to see how often it's presented as a given in the media. I tend to read WaPo more than NYT, but it's probably similar; while the comments there persistently complain about a rightward bias, I find that Trump generally comes across looking terrible (as he should when his behavior is fairly reported). Yes, there is mild criticism of Harris as well, but without that, the paper would come across as a pure liberal shill to anyone on the fence. And yes, Trump doesn't get fact checked on everything he says, but I think even his supporters at this point would admit that he lies regularly; that line of attack isn't really effective against him anymore, because it's baked into opinions of him. (Now, if a particular untrue thing he's said is winning him support, then debunking that would be another story. But it would also be newsworthy, and likely to be discussed in the msm.)

Expand full comment

Sure. There is no question that the overall reporting paints at the Times and the Post a far more negative image of Trump and Vance than Harris and Walz. My point is just that they are not applying the same journalistic standards consistently to both candidates. Overall, given how deeply unpopular Trump's actual policies are and how close this election remains, I have to wonder to what extent they continue to get played by Trump. For me, I don't have a problem with them pushing back on the Harris campaign and holding them accountable, but they need to make it clear that the breadth of misleading statements and exaggerations coming from the two camps is not remotely comparable. Otherwise they are essentially just both-siding their coverage.

Expand full comment

Yeah, I agree that's a fair point. It's tricky with Trump though, since he's so egregious that it's difficult to cover him fairly without looking incredibly biased against him to someone who might be undecided. So I'm not confident either way; you could certainly be right, but I think there's also a chance that going in that direction could just lead persuadable voters to write it off as biased.

Expand full comment

Completely agree that Trump is extremely difficult to cover because the normal rules don't apply. On some level, I think that both sides of the partisan divide think the other side is dumber than they actually are. I think anyone reading the Times, WaPO, WSJ or Fox News knows exactly what they are consuming. The left has been trying futilely for almost ten years to educate people on how terrible Trump is. The truth is that, as you said, many if not most of his supporters know deep down what a loathsome individual he is. But they also get something out of his leadership that compels them to vote for him. Sadly, I think it is often the experience of rubbing our condescension in our faces even if it ultimately ends up hurting them just as much.

If Harris loses PA by < 1%, her choice will naturally be questioned/criticized. "Let it go" is a fair response to this take if it were coming from a Democrat pundit, but it's a perfectly reasonable take from someone running a newsletter on election forecasting.

All that said, it's been nice to see someone like Walz in the spotlight. He's probably the most relatable candidate we've seen on a presidential ticket since... I don't know when. Definitely seems more relatable than Shapiro.

That's one opinion/characterization of things he's done and positions he's taken.

That's literally what turned Idaho and the Inland Northwest from a purplish eco-friendly but leans conservative region in the 60s and 70s into the far-right, white supremacist bastion that it is today.

Wonder why the recent fox news polls showing Harris leading in GA AZ and NV have either not been taken into account or are not making significant impact on the polling averages. Though foxnews polls are considered really good despite their overall conservative leaning

A lead of +1 for either candidate anywhere is meaningless. +1 is easily within the margin of error for any poll.

My sense is that the race is a tie and any small lead is just random error.

Being within the MoE isn't a random linear thing.

There is still a peak to the gausian curve, and 90% confidence has a smaller MoE than 95%.

If you want to go all the way down to 1 sigma, the MoE cuts in half again from 90%.

Random error is random error, meaning the inherent uncertainty involved in measuring anything.

Just eyeballing the most recent polls it looks like random noise to me: +1 Trump here, +1 Harris there, and so on.

Expand full comment

I think that is fair.

I figure that anything near 1% at the end of the campaign is within the realm of bad weather and good GOTV efforts, even beyond sampling artifacts.

At this point in the campaign cycle I am more interested in the movement in the polls and demographic coverage or weighting decisions.

I wondered too. The Fox polls appear to be listed as Beacon Research/Shaw & Co., based upon the results. I presume this is who Fox hired to conduct the polls.

For me, it’s best for Nate to remain the most conservative of the forecasters, and to allow that to motivate me into action. I’ll be canvassing in PA in October since it’s not far from NYC. If you want a rosier take, look at 538 or Race to the White House or literally everyone except RCP, who show Harris’s chances improving since yesterday.

Expand full comment

I'm not canvassing since live in Virginia which (2021 excepted) has been pretty safely purplish-blue but yeah even though I think he's overestimating the DNC impact I would rather be realistic than raise my hopes too high and have them utterly crushed like back in 2016. Too much confidence leads to hubris as we've seen demonstrated basically every election the last decade.

Still two big events left. Harris 1st interview, and Debate. Like @Bryan_Goldberg commented, I think this is a weird scenario we're coming thru, and more data in the next 4 weeks will make the picture clearer. But if I were Harris, I'd have Shapiro doing non-stop PA rallies, with the promise of a choice cabinet position in the future.

Expand full comment

Yeah, Pennsylvania is really non-negotiable. It’s too much of a risk to let it teeter-totter.

It doesn't even have to be a quid-pro-quo thing to motivate Shapiro. He'll want people amped up to go vote for Harris, because most will also vote for him. He's not a "distance himself from the party" kind of candidate, AFAICT.

'Recent' is doing a lot of work here... Yes there is an annoying lack of post-DNC Pa polling, but if you just look at page 2 of the Pa polling table, you'll see D+2.2, D+2, D+3, D+4, all polls less than 2 weeks old.

I think it's pretty clear the model is being too aggressive here, and that the assumed convention bounce was misguided.

Expand full comment

Given recent history what would have been the justification for not accounting for a convention bounce in the model?

Expand full comment

The fact that the last 2 presidential elections have seen little or no convention boost. I'd want to fit some kind of time trend on the convention boost. Seems like Nate's model just takes the average boost over all presidential elections for which we have polling data.

In 2020 the conventions were held virtually and IIRC suffered from a much smaller audience as a consequence. Even then there was sort of, kind of a bump for Biden in terms of favorability.

I think Nate is gearing up for a "should've picked Shapiro like I predicted" narrative should Harris lose. His occasional hinting that he was right about that, even after Walz's successful debut, seems to be a consequence of being too deep in the numbers without enough regard to the things that *drive* the numbers.

There's no way to know for sure, but Walz really seemed to keep Harris' honeymoon period afloat a lot longer than most, including me, would have guessed, and while "momentum" is a pundit myth, support needs to sustain in order to solidify. There's a reason the convention bounce is a "bounce" and not a lift, but the steady hum of good news, from the rollout though the VP pick and right into he convention, gives it a chance to hold (although of course the model is right to stay skeptical about it for now).

Harris needs Pennsylvania, yes, but she also needs the rest of the blue wall and more, and a slim win in Pennsylvania is just a good as a blowout. Maybe Walz wasn't "the River pick," but I can't imagine Shapiro driving the level of *broad* engagement (both inside and outside the Democratic base) that Walz has these past few weeks, which is what Harris needed to avoid a polling roller coaster.

But what do I know... I'm a Minnesotan who already knew how good Walz was as a politician and a Governor but wanted Harris to pick Whitmer (I think pundits haven't yet figured out just how much Clinton cracked that glass ceiling).

I think the two potential problems with shapiro are 1) that he’s too into his own ambitions to give the required level of deference needed from a VP pick 2) potential issues that came out of the vetting process. Even with the above I’m sure it was a close call between them

I'm just replying to have two 'LaCroix's' on the thread

When Shapiro was AG he maybe/sorta helped speed along a suicide ruling in a death where if it was ruled a murder one of his close friends would have been a suspect

It’s probably nothing, but when you consider how hard Republicans are trying to make literally anything into a scandal for Walz, avoiding the “Did Shapiro cover up a murder as a favor to his buddy?” news cycle easily could have been a good enough reason on its own to not pick Shapiro.

Tim Walz said that he carried a weapon in war -- he never went to war.

The Emerson poll seems suspect to me. Has Baldwin over Hovde by only 1 point. The Fox poll taken a few days earlier has her up over Hovde by 10 points and most other polling has her up between 5 and 10 points. Just wondering if the Emerson poll is an outlier? Most national polls have Harris getting a 1-2 point convention bounce but the Emerson data doesn’t reflect that at all.

Too bad there wasn't a prominent popular Democrat statewide official in Pennsylvania she could've put on the ticket.

Adding 1 point in Pennsylvania and losing 1 point everywhere else from vibes isn’t obviously a winning trade. (Not obviously a losing one either, but it’s very hard to know how different the vibes would have been.)

Expand full comment

What evidence do you have for 'losing 1 point everywhere else?'

Expand full comment

Exactly the same evidence I have for “gaining 1 point in Pennsylvania”. Nate suggests that there is enough polling data in recent election cycles to think that a VP pick of a state’s Governor for a state the size of PA would on average produce 0.4% gain. But the actual gain is not possible to be that confident in other than by assessing vibes and human factors that aren’t numerous or operationalized enough to have meaningful statistics on. Just like the impact of inflamed Gaza protests at the convention.

Expand full comment

Can't parse.

Expand full comment

If according to you it is very hard to know how different the vibes would have been, what is the basis for also claiming in the same comment that vibes will cost 1 point everywhere else except PA?

Expand full comment

CDC masking recommendation or Gaza or Mpox is all irrelevant here, you still did not give any actual hard evidence to the claim that the vibes will cost 1 point everywhere except PA while also saying it is difficult to quantify vibes. So you are making specific predictions while also saying that it is not possible to make specific predictions which makes no sense. Have a good one!

Expand full comment

There is no systematic statistical evaluation that can tell us anything about what would have happened had she picked a different VP. Nate suggests that the direct contribution due to picking the Governor of a state averages to 0.4%, but an average is very far from a confident guess.

If you want to insist that no one use information that hasn’t been statistically tested, then you get things like the CDC refusing to recommend masks and the WHO refusing to recommend mpox vaccines in Africa.

Right. My point is that this is the sort of thing, like vaccination or masking, where our best guesses really have to be made without a basis in hard evidence. We can't make predictions that are precisely supported by repeatable statistical tests. And that is the case for anyone who wants to say anything about what the VP pick means or meant.

Perhaps - we will see in November.

But right now, Nevada, Arizona, Georgia and North Carolina are in play, and they weren't with Biden.

There are a lot of combinations to replace the 19 EVs from Pennsylvania.

Expand full comment

My comment isn’t about Biden. It’s about Walz. And the most likely scenario in which Kamala wins the election is winning PA. Even with Nevada she’d still need to win AZ, NC, or GA (where she projects behind) and hold WI and MI which correlate higher with PA.

The most important thing is to win the election so IMO locking down PA and the upper Midwest is better than playing a larger map. Similar mistake to how Hillary tried to run up the score in 2016 IMO.

Shapiro would draw 2 points out of Michigan, making it a guaranteed loss and would put Minnesota in play. I think you're not fully comprehending how his pro-genocide views were scaring Arab and Muslim Americans, which make up significant percentages of those two states.

Yup - that was Nate's argument.

It is also possible that if Shapiro can't delver Penn as Governor, then he wasn't going to do it as VP.

As I said, we'll see in November.

Concerned but waiting until Mid-September to lock in my internal worry clock. Pennsylvania was always going to be tight and I doubt that state will ever be outside a margin of error so it was always going to be a white knuckle would be nice to be on the friendlier side of that though.
