Your insistance that "drugs' are somehow a problem that belongs to the coasts seems strange to me. Drug (and alcohol) problems are spread across the country and I can't see what they have to do with white southerners leaving the democratic party to vote republican. Wallace ran on his own American Independant Party ticket in 68 and won Arkansas, Louisiana, Alabama and Georgia. In 72 he ran in the dem primary and won one northern state - michigan - and a handful of southern states. I believe he won every southern primary that he ran in before getting shot. Significantly, his absence in 72 changed the result from a hairsbreadth win for the republicans in 68 to one of the most lopsided victories ever in 72.
