What if RFK had decided to sit out of the Presidential Race in 1968, and Nixon is assassinated by a radical leftist after winning the Illinois Primary (i.e. think the Weathermen.)? Will it be Rockefeller or Reagan who gets the nomination? Or will it be a compromise candidate? Who would they choose as a running mate? Can Humphrey beat the Republican nominee? Would the Electoral College deadlock thanks to George Wallace? And overall what effect would the person elected in '68 have on history?
