I'm from the WOW counties, a very Republican portion of them infact. The idea of them shaping back is silly and wishful (on the part of some R's). It was wrong before the election, and it remains wrong after the election. Congressional and statewide Republicans are continuing to do worse over time even though they outperform Trump. A Wauwatosa-Elm Grove-Brookfield district just flipped Dem in the assembly, a seat R's won even in 2018. There are serious concerns here for what used to be the heart of the GOP base in Wisconsin.
I also live in an assembly district that flipped Dem this year but I think that the WOW counties will swing back to the right once Trump is out of the picture, the areas that shifted left are wealthy and don't have much to actually gain from Democratic policies. There is no way Mequon, for example, would vote Dem if it meant that their taxes would go up. The reason why Donald Trump lost the state in 2020 was because a chunk of suburban WOW Republicans never liked him personally, but a lot of them voted Ted Cruz in the 2016 primary and are still conservative voters.
