I think you guys really underestimate how hard of a floor there might be with Southern suburbanites. All they're doing is reverting to the "norm" of America and becoming more of a swing demographic like their Northern counterparts. Even if the GOP literally moves to the left of Josh Hawley on economics and becomes this "working class" party, you're still going to have a VERY high percent of Evangelical voters in these suburbs who are simply Republicans first AND educated suburbanites.
Younger generations are less religious though, which is why I think that floor might collapse in the future. Not necessarily within the next 10-15 years, but 20+? Maybe...
