That is quite true, but some red states are turning a bit blue around the gills too, due to demographics shifts. I was wondering about SC because my familiarity with the state is very out of date.
SC is no where near NC in that regard, and yes, you are right, the yankees are moving down to the south and then voting the same crap they escaped in their new home. It’s shameful, and I’m sure some of that is true in SC, especially around Charleston and Greenville, some in Columbia, but not nearly the situation in NC.
