Wallace voters tended to be poor. Actual KKK members probably voted for Wallace. Nixon appealed to wealthy Goldwater voters who, even if segregationist, didn’t care for Confederate flags or Robert E. Lee statues. Nixon voters never again voted Democratic while some Wallace voters voted for Carter. In fact, Wallace himself endorsed Carter, as did Eastland.
Southern Senator is an expert on this.
A proportion of Wallace voters probably voted for Mondale, Dukakis, Clinton and Gore.
Nixon voters if suburban and wealthy/middle class stayed loyally republican, however if more rural and in unionist areas some of them switched over for Clinton, Carter and even Gore.
I agree about both the Nixon and Wallace voters generally. I would say that an overwhelming majority of Wallace 1968 Southern voters still alive enthusiastically backed Donald Trump in 2016 and 2020, whereas most surviving Nixon 1968 Southern voters probably backed Hillary Clinton in 2016 and Joe Biden in 2020.
