I think for a lot of these wealthy Republican suburban counties it's either 2020 or not in the forseeable future. It's hard to find a Republican more toxic to wealthy conservatives than Trump. Even if they nominate Cotton or so he'll definitely do better than Trump with wealthy voters. Romney won people earning over 100k 54-44 while losing 51-47 overall. GWB outperformed similarly with wealthy voters (58-41 with wealthy voters vs 51-48 with the general electorate). If the Republicans nominate Pence or Cotton (which is a big if though) in 2024 wealthy voters probably will go back to the Republicans, especially if the Democratic incumbent is someone like Warren or Sanders.
Why would the GOP/RNC want to go back to campaigning like Bush and Romney after Trump electoral win was larger than both of them. Also what if the Sanders wing of the party don't take over which is looking more likely every day after Perez, Northam, and Bauman victories.
