I think we're headed towards a decade of D presidents once TX goes, the question is when that is. If Trump wins this year, it'll vote for the D in '24 imo. The math just isn't there for the GOP to win when the presidency with it D for the time being.
The GOP is going to start owning the rust belt and great lakes states, including MN. That, with FL being increasingly republican, makes up for TX.
Yes, there is a big trend among white retirees moving to FL and helping it stay red. A big problem for Republicans is that from 2012 to 2016, the minority share of the electorate went up by 6% in only four years. Non Cuban Hispanics, and young Cubans are also driving the state in the opposite direction. Whites in FL are becoming more Republican, but are still losing as a share of the population. The demographic time bomb might erupt in FL in 2024.
