If longtime Republican NY Governor Nelson Rockefeller, the leader of the GOP's moderates, had avoided his 1963 marital scandal he no doubt would have been the party's standard bearer in 1964 instead of Goldwater. He would have lost that year, but like Dewey in 1948 he would stand a good chance of winning the nomination a second time in 1968. Rockefeller, who polls showed was the most nationally electable Republican, would easily have beaten Hubert Humphrey had he - not Nixon - been nominated in '68. Supposing that President Rockefeller takes office on January 20, 1969, how would his administration play out and how does this alter the course of American history?
