Another big question mark in Florida now is the crossover votes. It’s being hyped up that Biden is getting a nice amount of crossover votes from senior Republican voters so we’ll have to wait and see on that. I also personally believe there will be less Democratic crossover votes for Trump this year because a lot of Dixiecrats have changed their registrations to Republican since 2016.
I read somewhere, but I'm not sure of the validity. That 16% in Sumter county Republicans voted for Biden compared to 10% Dems for Trump.
