In this election, the Republican trend of whites in northern Florida and exurban areas slightly outdid the Democratic trend in Orlando and Miami that was expected. Overall, the state is not trending much, but what will be fascinating is to see just how Democratic Miami-Dade can get, and will the deep south area to the west and east of Tallahassee keep getting more Republican? Florida is no lock for either party at the presidential level.
I was wondering this too but first we would need to see if Miami-Dade goes towards democrats in other races:
For example: in FL-25, FL-26, and FL-27 which are all controlled by Miami-Dade based Republicans, Trump only got 49.6%, 40.6%, and 39.1% of the vote, respectively. It will be interesting to see if Democrats can try to make a play at these three seats. Two of the three incumbents are pretty entrenched though so it would be tough unless they retire.
Remember, the 25th also extends into the Naples area, and even with Trump, Hillary couldn't win it. Mario can have the seat as long as he wants it, and even when he retires, his successor is almost certain to be a Republican. I think post-Trump, the numbers go back up a little (not to pre-'08 levels, but I think Trump hit a floor).
