A segregationist who changed their views on race sometime between 1969 and 1983 and became a very liberal Democrat after they changed their views.
I mean, I know this site regularly quibbles about this, but this type of voter was most likely a very liberal Democrat ALWAYS. They were simply a liberal Democrat that supported segregation and then one that got over it. A lot of those people existed, and it's not productive to sweep them under the rug to try to make ideological sorting of the parties into some simple affair.
Especially since economics was probably the area that George Wallace differed the least from Bernie Sanders or Jesse Jackson.
Exactly. There were obviously many very conservative Democrats - even on economic issues - that were ardent segregationists, but there were also many who were more liberal on these issues. The point is that "Southern Democrats" (and, by extension, "segregationists" for much of the Twentieth Century) was a broad term to describe a very ideologically diverse, big tent group. Even if one wants to maintain that supporting segregation is an inherently "socially 'conservative'" position (I do not agree, but that is beside the point), it does not make all segregationists "conservatives."
