At the presidential level at least, it looks like it went through several stages of these suburbs being realigned to Dems
1992-1996: northeastern and california suburbs
2008: NOVA, research triangle NC, Chicago suburbs, Denver suburbs
2016-2020: Atlanta suburbs, Phoenix suburbs, further erosion in DFW and traditional GOP suburbs such as WOW counties of WI, Delaware OH, Hamilton IN, El Paso CO.
Sounds about right, how can the Republicans take the suburbs back or at least hold onto them?
They can’t. They can only minimize losses. They’re about to lose the last holdouts which I think would include all the DFW counties, OKC, Chattanooga, etc. This of course assumes MAGA's continuous grip on the party at large.
