JFK Lives -- Who's his successor?

[cmt]

JFK lives.  His successor wouldn't have been AG Robert Kennedy.  Even if JFK were still popular I don't think that we can automatically assume his brother would succeed him.  It would smell like and be nepotism.  We also don't know how the world situation would have been in '68 with JFK.  I believe we would be involved in Vietnam in some way, but not sure if it would be as bad as under LBJ.  I also don't think VP Johnson would be the Democratic nominee.  I could see Hubert Humphrey, Scoop Jackson, and others going for the nomination.  I think there is a good chance that if JFK lived and the country was ready for a change in '68 that it might be Nelson Rockefeller or George Romney.
