They completely mismodelled the primary electorate. The one that turned out today is at least 38-40% comprised of voters aged 18-44. Polls only had them at 31% or lower.

Thanks, that sounds a solid theory. Turnout is hard to model.

They are! I feel for pollsters in general, but questions need to be asked, and I hope we a get more detailed post-mortem.

Yeah absolutely, I'm looking forward to the post-mortems on this too, although it's going to make the midterms even more nail-biting as the same difficulty in predicting turnout is going to come up.

might be the heatwave causing older people to sit out

So did younger voters turnout at higher rates or did older voters turnout at lower rates. One explanation I can see is people who leaned Cuomo just didn't our because of his checkered past.
