Trust me. Puerto Ricans are a big part of the FL Hispanic population, and we hate him just as much.
Do we know how Puerto Ricans have voted in the past in FL? I haven't found that level of detail in any exit poll.
Not that I know of. I believe Latino Voices have done some polls or Puerto Ricans in FL though, and it's something around the 73:27 split from what I remember seeing.
Anecdotally and culturally though, Trump is a horrible fit, and Hillary is well-respected among Puerto Ricans.
Also, keep in mind that Clinton won PR in a landslide during the primaries, while Rubio ran away with 70%+ of the vote. Now, there may be racial/ethnic factors in play here, but it doesn't exactly look like a Trump-friendly demographic.
