Rockefeller in '64 and Goldwater in '68

if Nelson Rockefeller won the Republican Nomination in 1964, is there any way Barry Goldwater could win in 1968? and if Barry Goldwater ran in 1968 he win the General election?
 
The easiest way would be JFK lives, maybe his cheating ways get out or he overextends on civil rights, Rockefeller narrowly beats Goldwater and in doing so seriously pisses off the conservatives, Rockefeller narrowly beats JFK, Rockefeller has no better than average four years, Goldwater trounces him in the primaries, Goldwater (almost certainly) loses to generic Democrat.


Goldwater is always the steep underdog in a general election, with '64 vs. JFK with JFK scandal his only real (if slight) chance.
