This is my map. I’m essentially just pretty reserves in how many of these trends will actually pan out into real EC results in that timeframe. While they’ll definitely be closer, I‘m sort of doubtful states like Texas, Georgia, or North Carolina will ever have an actual shot at going D. The only changes I feel sure about are the ones that are clearer.
So for Ds, VA, NV and CO become solid D. Arizona becoming tilt D and Montana tilt R are the only places where the demographic shift shows up as electoral results on the actual map. Meanwhile NH, Maine, and Minnesota become more favourable to Rs for the same reason, but still Tilt D overall. The Rs gain in Ohio becoming a solid R, Florida and Michigan become strong tilt, and Wisconsin and Pennsylvania becoming Tossup (Wisconsin has a lean R, and Pennsylvania has a Tilt D, by they are the most malleable states).
This is all assuming the parties run the current sort of “establishment” candidates with the type of “establishment” policies they currently have. The map can change hugely depending on if the candidates running change (EX. Rs go back to a pre Trump style candidate, Rs go for extreme right-wing populist (but an actually ideologically committed one, not a Trump lol), Ds run a left wing Sanders-type of candidate, Rs run neocon, Rs run libertarian)
