Thank you for posting the list. The list is why there are Democrats who seriously insist that the two parties changed names over the years. With no reasonable explanation for their long bloody history,they choose to propagate the fantasy that Dem ideology which liberated the slaves was, at that time, called Republicanism and that Repubs ideology was at that time Democrat. But social shifts etc. caused the two change places! YES! I’ve seen it argued. Unbelievable! And that argument was put forth on the web vigorously even as the debate about former KKK leader (Dem) Senator Byrd was in full swing!
What they don't mention is that over 90% returned to the Democratic Party and only a handful switched to the GOP years later. They also say Nixon tapped into the southern Democrats to win his election, because those Democrats were former Dixiecrats and the GOP won the south for decades thereafter.
What they don't mention is GOP presidents just before (Ford) and after Reagan (Bush, Bush2) actually struggled to win the south decisively, especially when going against Carter and Clinton (2 Democratic southerners)
