What if, during the 1972 presidential election, George Wallace decided to again run for president on the American Independent Party ticket? In that year, the AIP nominated the unknown California (bad) Republican (worse) Congressman John Schmitz, who was so far-right that he was expelled from the ultraconservative John Birch Society for "extremism." This was a little too much even for the Southern segregationist voter. If the much better-known George Wallace ran, he may well have done very well in several Southern states, taking the votes from those who were rather wary of voting either for McGovern or for a Republican, and presumably would throw a big wrench in Nixon's "Southern Strategy," if he even attempts it at all.
What would be the effects of Wallace's campaign, and the delaying or altogether preventing the North/South realignment of American Presidential politics?
