why is that Jackson THAT Republican? That's pretty damn solid, even for Kentucky.
Mostly for Civil War reasons (very little support for slavery in the mountain counties all over the South) and because people take after their parents, who take after there parents etc. etc. etc.
It's like that in most areas to a certain degree.
IIRC pretty much all of South Central and Eastern Kentucky
was solidly Republican up until the New Deal, when the Eastern Coalfield went over to the Democrats.
South Central KY is more Agrarian and is very isolated and didn't switch.
