I just don't understand where a Trump lead would come from is all - hispanics are turning against him, and there hasn't been any polling showing Trump doing any better than Romney with white voters.
Look at the early vote numbers. Obviously, things could significantly change today since it's likely to be the heaviest pro-D day with all the church-sponsored stuff, but Trump slightly ahead between absentees and early vote. Unless this somehow changes over the next few days, you're looking at an R+ electorate in Florida, which favors Trump.
Republicans traditionally vote on Election Day there. Democrats use their padded lead to stave off any Republican advance.
