His model and 538s have both produced outcomes where one candidate gets 520+ EVs.
He assigns the quality ratings to polls himself and publicly announces them. They’re based on whether or not they predicted the outcome of the election.
It’s his very poll scoring system that causes polls to herd. Because even if they’re wrong, they’re wrong together.
He determines the weights of those polls and chooses how to apply them.
Nate has done plenty.
This seems to me like a signal that Democrats are formally cementing as a conservative / neoliberal party. Which makes sense. I guess maybe the upside is that maybe it will carve out room for an adjacent political body to the left as well, sort of like what happened with the tea party.
