I'll be honest, these maps are underestimating. If the Republicans were THIS damn overt, they would not do nearly this well. Keep in mind that even a significant number of REPUBLICANS have turned against the party in this case, and the party is deeply unpopular, given that Trump (who through fair weather and foul has always had his supporters loyally approving of him) has such abysmal approvals. A further point is that while the Culture War issues (i.e. gay marriage ban and abortion) will be less problematic in Appalachia, the stark opposition to entitlement programs will have a more acute effect (that, after all, is the reason Bevin lost in 2019, and that's the reason even the most extreme Republicans come short of outright condemning Medicare/SS). Oh, and don't forget Cooper and Beshear are no AOC's or Harrises - they are the PERFECT Democratic candidates for red states in the Deep South / Appalachia.
Here's my guess, given all these factors:
Yeah at first I would have agreed with Tekken_Guy's map because polarization is so strong these days, but a Republican running on a platform to ban ALL abortions and end social security & medicare is equivalent to the Democrats running on a platform of actually abolishing the police & prisons, so a map like this could happen.
