All my Gray hair Family in the South stayed Democrat until they died , Think
Robert Byrd (D) the Party switching is a fantasy of the left ( George Wallace (D) woulda beat Nixon in 72 if that crazed Republican in the Black Turtleneck had not shot him , he won Michigan & Florida Dem POTUS primaries and was on cover of TIME magazine as our next President .) Carter won on Wallace’s coattails in 76 . And just because some Democrats voted Reagan once or twice does not mean they switched parties . From 1870 until 1986 when it was litigated out of existence eight out of every ten members of the Knights of the Ku Klux Klan were Democrats ( or Dixiecrats if that offends you )
Little offends me other than wilful ignorance, poor firearm handling, and political and religious speeches full of empty platitudes.
I was speaking of the parties switching not their supporters. When someone is thoroughly brainwashed attempting to change this can confuse them and break down their programing.
It's much better and easier to just gradually alter the lies they're fed to support the programing with "
alternate facts" so they still respond as programmed but their focus is now pointed in a different direction.
The Klan didn't disappear; like a corporation declaring bankruptcy it simply stopped using one name so it was no longer liable for any debts or rulings against it and reformed and reappeared under a different name selling the same shabby products with a different label.
My kin folk were/are split. North of the Mason Dixon line generally they were/are radically conservative Republicans and south of the line generally they were/are radically conservative Democrats.
Though listening to them talk you wouldn't know which was which until they started assigning blame for the ailments of the country.

IMO the ultra dedicated and devoted members and supporters of both parties are nothing more than the human equivalent of Pavlov's dogs or cell phone users who cannot
not answer their phones.
