SearchlightSince we're discussing 538, does anyone know whether they factor in early voting? Obviously you can't expect an early vote to automatically fall in line with the state of the polls when it was cast, but maybe there are tools to price in that sort of stuff.
I've looked for this but as it seems to be a pretty new thing I don't think anyone is confident enough to model it seeing as there isn't much historically to go on. There have definitely been a sizeable chunk of early votes cast in a more Trump hostile atmosphere, but at the same time the Clinton backlash was pretty big in the last few days too and who that might motivate to turn out early and why is open to question.
If Clinton takes a lot of states that have ended up polling on a knife edge then it could certainly be a reason why, I'll be interested in how it gets unpicked after the election.
