At this point, national Dems should just concede FL and hope it becomes a natural GOP pack consistently won by a couple million votes so they can make up some of the EC bias.
Disagree solely because the GOP is
DONE nationally without Florida. This is why the GOP has placed so much emphasis on turning the state red; they were canvassing/doing voter registration drives in Miami-Dade in spring 2017 like it was the fall of an election year because for them it might as well be. The basic math of 2 Senate seats and Clinton states+FL+any Trump-Biden state>270 speaks for itself.
It is true demographic trends with retirees/snowbirds and the infrastructure gap with reaching out to Hispanophones both strongly favor the GOP; However Dems need to play offense in one of Texas/Florida. You can't afford to have 2 of the 3 largest states off the board before a single ballot is cast.
