2. Polls consistently indicate Clinton is leading and leading big among early voters.
It depends on how well Obama was doing in polls among EV. For instance if he was doing ~better, then it is nothing strange at all. And MOE should be taken into account.
Otherwise, it could indicate some sort of realigment (that would not shoke me).
It looks like the FL/NC polls are backwards, with NC being less diverse, Florida being more diverse (Latinos more than offsetting lower Black share).
What is raw numbers of EV by race in Florida 2012 vs 2016?
I guess that's possible but it'd imply white early voters differ enormously from white election day voters. Is that the case?
