I agree and disagree.
We make the assumption that Humphrey who was absent from the primaries would have won the nomination if Kennedy had lived from the idea that Humphrey was the favoured of the party bosses.
But I do wonder given that Kennedy's candidacy was not incredibly strong until May and was in fact building momentum by the time he was killed, and if that had carried on the Convention where there would have been incredible pressure. Don't forget it was less than 5 years since JFK's assassination - I don't doubt that many many people would have voted for RFK for that reason alone.
Assuming RFK got the nomination - and the eventual result which wasn't close in the electoral college (but the popular vote shows that in a few states it wouldn't have taken much to swing it. Kennedy could've run on his brother's legacy, and the anti-Vietnam ... it would've been close, but I think RFK would've won it in a sqeaker.
RFK - 278 (Winning WI, VT, NJ, IL, OH and DE extra)
Nixon - 215
Wallace - 45
