#VAGov polls have largely been junk, but Youngkin can win this race. But the early vote suggests that turnout for both sides will probably be fine, so if he wins, he wins by swinging significant amounts of college-educated voters (specifically college-educated whites).
No polls have been showing a significant swing right with college voters, though. They've either been showing the race close because Black voters swing right by 35 from 2020, because non-college whites swing right by 25, or because their partisan screen is ridiculously R-heavy.
I find the "non-college whites swinging right by 25" part a bit questionable because Trump's support is already very, very high in most of the rural white areas, so unless you've seen a catastrophic collapsed with Virginia urban whites (questionable?), I don't see the math.
If polls get the topline right, they'll have gotten the path entirely wrong. If one has an electorate that's 75% college educated that shows a D+1 race while another has an electorate thats 60% Black that shows an R+1 race, the average is a tie. But they both suck!
You shouldn't get credit if you whiff on the electorate composition or miss on crosstabs *outside* the margin of error just because you accidentally got the topline right. It's malpractice to suggest otherwise and masks serious problems with US polling to take it as acceptable.

Every poll has two parts: the electorate screen and the margins among the demographics. The electorate screen is where you give a representative sample of what you think the electorate will look like. The crosstab margins are the margins among those groups. 🧵
If the electorate screen is broken, there’s a problem. It means that the poll will not be representative of the state. Because fundamentally, you’re giving the results that would occur in an electorate different from the one that actually exists. Allow me to construct an example.
Say that a state is 40% Black, 20% Latino, and 40% White. Your poll would probably want to match up in terms of demographics — You cannot poll all 3M voters in the electorate, so you need a good sample to allow you to approximate what you think the electorate resembles.
Given recent polling trends, the model's converging to ~D+5, in my read. That'll likely be what our forecast ends up as (and thus on the border of lean/likely Dem too). The confidence interval here would be D+2 to D+8.
If I had to be forced to pick, I guess I'd take the under? Just because it's not really statistically safe to rely on a polling miss of >4 points even accounting for the flaws I've discussed. But honestly, I'd just go with the forecast, because my punditry has never been great.
I think a lot of the polls aren't great, but part of analysis is setting your rules beforehand and then following them. We add in just about every poll we can *unless* it's from a banned agency or violates our pre-set rules on internals/data quality/data collection procedures.
Model updated for #VAGov with the new @Suffolk_U poll. The forecast from @Thorongil16 and me is D+5.8. Suffolk is the second high-quality pollster to show a close race, so let’s dive in 🧵
I will say this: if you firmly believe crosstab examination is not a useful exercise, please stop reading. Nothing I say will be of any utility to you, because we have fundamentally different ways of going about this. Save yourself the time and stop reading.
Suffolk’s poll only has an N=500. You need to be careful with the window of results you consider as a result. Anyways, the racial crosstabs are okay; McAuliffe wins Black voters 81-8, and I would wager that undecideds here are expected to break Democratic.
Emerson has been banned by us for a month now because of MTurk data quality issues. Not including it regardless of what the poll says.
Also, the n=145 among Black voters here. A 36 point swing right would be well outside the margin of error for the Black subsample.
I need to stress that *I COULD VERY EASILY BE WRONG*. All I'm saying is that if Youngkin wins, the path to victory will look *nothing* like what these polls suggest. Data points to a McAuliffe win, but if D turnout is low or Youngkin swings suburbanites, it could change.
Heading into the final week or so before the election, here’s how @Thorongil16 and I have things shaping up for #VAGov. We still have this race as fairly stable and think McAuliffe should win by about six-and-a-half points. His odds of winning are a bit over 80% (likely D).
Democratic early vote has really surged recently, as folks like @samshirazim, @ZacharyStarbuc1, and @WinWithJMC have noted. This week will be crucial for Democrats, but they had a very good weekend and continue to see their base areas go up in share of statewide votes cast
As folks like Zachary and Sam have noted, NOVA will likely be fine for Democratic turnout. Areas like Richmond are lagging a bit, but that probably isn’t enough for Rs, who currently have their own troubles with getting whites in Southwest VA to remember an election exists.
Points in favor of a Youngkin victory: Biden's approval is horrific, so independents might break R, and and Democratic turnout is undeniably lagging currently, so you could see him eke out a 1-2 pt win.
Points against: Virginia 2012-2020, and he *still* can't clear 46% in polls.
That last part is especially telling for me, because in every poll, the undecideds have been disproportionately Democratic, and we know from a lot of polling data that split ticket voting is quite low in this race right now. So the median scenario shouldn't be a tossup IMO.
Polling already seems to price in a Republican turnout/enthusiasm advantage, and even with that, Youngkin isn't crossing 46%, which is a problem. People are eventually going to decide, so he'll have to get a good bit of crossover votes he's not currently getting.
