You have obviously not taken an American History class....or read ANY books about the development of the country....more’s the shame.
For the record since the 1970s the south has on a federal level voted pretty reliably republican ( at least for president). The south is full of folks who believe in states rights, many of whom are still mad about Lincoln ( not all though), and who believe in local politics. Unfortunately too many of them in times past have voted the ‘family tradition’ instead of what is best for them. The republicans turned the view point around with Barry Goldwater in 1964 and Ronald Reagan in 1980. This is not a RADICAL shift is was the realization that the left had moved so far into communist territory that they wanted none of it.
Do some reading it will help you out in the long run
To be fair, American History in schools is taught from a hard left point of view.
That anyone asks questions after that is a significant mark of intelligence. Schools say, “if you question, you must be racist.” which tends to shut down debate.
“Shut up.” is the standard liberal argument.
