So you're saying the [Democrat] governor of Alabama was pro-segregation? Call me shocked, boy!
Also, when George Wallace was running pro-segregation campaigns he was mostly doing it under the AIP - American Independent Party Ticket. A far-right (conservative) independent political party.
The term, Dixiecrat, was literally coined for Southern racist Democrats like George Wallace, who had too much Southern Pride to give up the Democratic Title, to separate him from what is the Modern (Liberal Northern) Democratic Party.
That's one thing that never changes in America. Demographics. When Republicans freed the slaves in 1860s, they were Northern Liberals. Just as when Democrats ended Jim Crow and Segregation, they were northern Liberals as well. Leadership changes and voters fall in line for who represents them. That is how the vast majority of black, who had previously supported Republicans up until the 1930s, virtually jumped ship to the Democratic Party by the 1960s.
That's basically how every push for civil rights goes in America. Supported by the more Liberal North, and resisted by the Conservative South. And even today with Gay and Trans Rights. Tolerance towards immigrants, refugees, etc.
