I don't think Trump can just cry socialism and all the sudden Cubans who voted for Hillary are in Trump's camp. This is partly a generational shift and a long term problem for the Republicans in Florida. So while it could get slightly more Republican in 2020, I doubt it's by a substantial margin or by a margin that makes or breaks the state at large.
Yeah people think because they bounced back in 2018 from 2016 that its gonna swing R in 2020.
Reminder that I am pretty sure Obama either lost or only narrowly won FL 27th in 2008 which is now Clinton +20 after going to around Obama +8 in 2012 I think?
