Cubans trended sharply D even in 2016, look at Dade county. Trump did terribly there but won Florida because of his big margins in formerly close white working class areas like Volusia, Flagler, Pasco.
Correct, but some of them just were embrassed of the Trumpster. Rubio won his race by a decent margin. If some of these Clinton/Rubio voters return to the GOP, especially if Pence is the candidate, and Dems can't significatly increase their number of voters through a higher turnout, the GOP is somewhat favored to take these pivotal 29 electoral votes again. Even though I still believe that the Dem's path to 270 is somewhat easier without FL than for the GOP.
