Is this because of boomers moving to Florida or have Florida Reps outplayed the Dems?
The disparity is because MAGA has gradually become more entrenched throughout the red parts of the state, and more importantly because Trump has solidified Republican votes in the state's three biggest Dem counties of Dade, Broward, and Palm Beach , particularly among Dade Cubans who although historically Republican, had been drifting more Dem due to a new generation of Cubans with different attitudes coming up. Trump appears to have turned that back around. More broadly, he out performed himself in each of the three counties from 2016 to 2020 and will probably very well again in them this time.
