For the oligarchs the greatest challenge has been getting Greater Appalachia into their coalition and keeping it there. Appalachia has relatively few African-Americans, a demographic fact that undermined the alleged economic and sexual “threat” raised by black empowerment. Borderlanders have always prized egalitarianism and freedom (at least for white individuals) and detested aristocracy in all its forms (except its homegrown elite, who generally have the good sense not to act as if they’re better than anyone else.) There was — and still is — a powerful populist tradition in Appalachia that runs counter to the Deep Southern oligarchs’ wishes.
That is from Colin Woodard’s American Nations: A History of the Eleven Rival Regional Cultures of North America, a book worth rereading in light of recent events.
