In general terms what's going on in these counties is they're nearly white white is honestly pretty rare in the deep south states - many of these counties only have like 1% black population which is crazy for this region of the US.
Realistically, Republicans are probably maxed out or close to it in terms of %, but these counties have pretty mid turnout so if Republicans were to theoretically invest in the region they could probably squeeze some more raw vote margins out of them.
As for not voting the same as the rest of the south during the "soldi south" era not being as much of a plantation economy was probalby a factor - this region seems unique in that it's culturally southern but economically more like Appalachia
There’s zero political benefit to turning out these voters because every office they can vote for is unwinnable by Democrats.
