A little bit of alternate history that I don’t think we have ever covered in GD
So, Richard Nixon doesn’t slam the car door on his leg. Then for the debate with Kennedy, Nixon wears full make-up. Now Nixon doesn’t look quite so much like a criminal in that debate. Nixon carries Illinois & Texas in route to a close electoral victory.
IIRC, Nixon is still the 2nd youngest president ever elected [had he been elected], so while not “young & handsome” like Kennedy, Nixon would have just turned 48 in January 1961.
Nixon paranoia: not feeling cheated out of a victory in Ill & Texas, and losing to Pat Brown in '62 CA governor’s race Nixon is not quite so mistrustful of his “enemies.” The Nixon White House has no “Plumbers.”
Viet Nam: Nixon, with the anti-comunist bona fides, does not feel pressured to get involved and Asian land war the way JFK & LBJ do.
President Henry Cabot Lodge: Lee Harvey Oswald still assassinates the 37th president. Does Massachusetts become so “liberal” as the Kennedys perhaps don’t become ascendant in MA.
Would the Civil Rights movement been changed? No Goldwater defeat in '64, therefore no 'Reagan Revolution" in 1980?
BTW, interesting piece of “vandalism” in Nixon’s bio in Wikipedia right now.
