Suburban southerners are racist hicks.
But even if they weren't, a basic look at the 1980 map shows the counties that Carter won are either black or within the TVA. So, actually, Reagan did very well with Wallace voters.
Living in the suburbs and being a hick is contradictory as the term "hick" refers people who live in rural areas. Also, TVA Democrats WERE Wallace voters for the most part... did you even look at the 1968 map? You also conveniently forgot to mention Arkansas, SW Louisiana, SE Texas, Northern Florida, Georgia, and chunks of Alabama, Mississippi, South Carolina, North Carolina and Virginia that can't necessarily be explained away by the black vote. Its pretty obvious that most of the rural Wallace vote was going to Carter in 1980, especially factoring in 12 years of generational turnover.
