As we covered in that other thread, FL registrations are down almost 5% (719,825 fewer voters).
Trump won 5,668,731 last time (51.22%), from a 75.98% turnout of 14,565,738 registered voters.
Assuming identical turnout, the same share of the current 13,845,913 would be 5,388,588 voters (-280,143).
If he increased his absolute vote count from 2020 in Florida it would require capturing (53.88% of the votes cast (assuming same turnout rate).
All that to say, if you want to bet on whether Trump increases his share of the vote relative to 2020, I'm game.
I wouldn't make a bet on the absolute count because of the decrease in registrations.
