Wallace will not win the Democratic nomination. He can win many primaries, including Midwestern ones such as Michigan which will cause the Democratic establishment to pantshit. It will show that Wallace still has a strong blue-collar following and not just on race. The same thing happened in 1964 when Wallace nearly beat Indiana Gov. Matthew Walsh, a LBJ proxy, in Walsh's own home state with a formidable Democratic machine on Walsh's side. In 1968 Robert Kennedy locked up the blue-collar vote (including many Wallace voters) in the Democratic primaries and the Dems breathed easy. They didn't realize though not a few of those blue-collars who voted for RFK voted for Wallace over Nixon in November, in retrospect a warning sign for both the Democrats and Nixon. Wallace cannot win in the North, but he can be kingmaker and potentially cause a convention deadlock unless McGovern (the presumptive nominee by May 1972) makes concessions. That's not happening, but Wallace had already made arrangements with Nixon in January not to run third-party. If Wallace had run third-party, it would've dented Nixon's margin, but not enough to make a difference in the electoral vote.
