Why did Romney Lose Florida?

[Skill and Chance]

There is also a large homosexual population down here in south FL, and they went heavily to the President.

This is true.  The national exit poll actually had a 49/49 statistical tie between Obama and Romney among straight people, which is just crazy to think about because that's 95% of 2012 voters.

Hispanics, and more precisely Cubans, probably put Obama over the top as they swung heavily Democratic. If they were at 2008 levels Romney probably would've won the state.

If that's true, it would be remarkable, since Cuban Americans have generally been one of the most solidly GOP voting blocs.

That trend has been weakening, especially amongst younger Cuban voters.  If the statewide Democratic Party were stronger here in FL than they currently are, Democrats would be mopping the floor in statewide races.

It will be interesting to see if Cubans swing further D or a bit back R after Obama's diplomatic actions regarding Cuba.  I think it will be the latter.
