Wisconsin up 12 D -- Wisconsin must be very close to a Republican win if not a state voting R if the Republican nominee is to win the Presidency.
Wisconsin, 56-44 D? 2008 redux. That means that Florida and Ohio are both going for the Democrat.
Ohio and Wisconsin are two completely different environments this year. Their Republican Parties have different bases, socioeconomic demographics, expectations for governance, etc. Anecdotally, almost every Republican I know in Ohio is voting for Trump while most of the Republicans I know in Wisconsin won't.
Anyway, I suspect the undecideds really are that high in Wisconsin right now, though they aren't so much undecided and determined not to vote for either candidate.
