I really doubt that FL will turn Blue. Voters in FL are too fucking dumb and numb. After all, Floridian voted that loser Ron DeSantis as a governor and he is a moron.  

However, TX is an interesting case for following reasons:

Texas Population in 2016: 27.5M, Registered Voters: 15.1M, Turn out at 52% with Trump getting 4.6M and Hillary 3.85M, Gary Johnson 286K and Jill Stein at 75K;

Fast Forward to 2020

Texas Population in 2020: 29.0M, Registered Voters: 17.0M and already 4.8M voted and that is with no third-party candidates and 14 days before election.

My gut feeling is the GA will turn blue (surprise), and TX may have a better chance of going blue than those dumb fucks in Sunshine states.
