The incredible thing is that Trump would still have won without Florida. There would surely be a Michigan recount circus until mid December, but Clinton would still have lost (on the off chance the recount flipped the outcome, the MI legislature would probably vote to assign the electors to Trump directly and then SCOTUS would have to rule on the validity of that move).
Well if Trump lost Florida that means his voters (rural whites) aren't turning out so he'd likely lose Pennsylvania, Michigan, and Wisconsin as well.
Not necessarily. In Florida, it could just mean that Clinton really was getting 10%+ more of the Hispanic vote than Obama like many pollsters expected to cancel out the rural white swing in the rest of the country. Clinton's PV margin would be ~3.5%. Arizona would probably be recount level close as well and Texas would only be a 4-6% Trump win in that world.
