What Papa is talking about with the quote is the '58 Alabama election in which Wallace had the support of the NAACP, while is opponent John Patterson was supported by the Klan. (Patterson was from the town I grew up in, the scandalous Phenix City, Alabama)
Patterson won in a landslide and suddenly Wallace became a huge segregationist.
His motivations always seemed based in a thirst for power.
I think by the mid sixties he believed his rhetoric, but he never went as far as to pass out ax handels to voters so they could beat any Black person who tried to vote, as Lester Maddux the regretable governor of Georgia did.
I stand corrected, you are as vapid as they say.
