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)
Thank you - I appreciate the background.
