You know what? As I was creating the graph, I thought I remembered someone else making these trend maps. Looks like I was right! Thanks for helping me out Antonio! Your map is pretty much on point with my results, but goes back further.
I made an entire thread dedicated to this kind of analyses (with tons of maps and graphs). You can find it here :

As for Florida, it's hard to say where it's going, but in the long term I think it might become lean-D (say in 15-20 years). Right now, though, democrats should focus on other States like Virginia and Colorado.
