Political historians still debate whether Kennedy could have won the Democratic nomination had he lived. Some historians, such as Theodore H. White and Arthur M. Schlesinger Jr., have argued that Kennedy's broad appeal and famed charisma would have convinced the party bosses at the Democratic Convention to give him the nomination. Jack Newfield, author of "RFK: A Memoir", stated in a 1998 interview that on the night he was assassinated, "had a phone conversation with Mayor Daley of Chicago, and Mayor Daley all but promised to throw the Illinois delegates to Bobby at the convention in August 1968. I think he said to me, and Pete Hamill, 'Daley is the ball game, and I think we have Daley. However, other writers such as Tom Wicker, who covered the Kennedy campaign for "The New York Times", believe that Humphrey's large lead in delegate votes from non-primary states, combined with Senator McCarthy's refusal to quit the race, would have prevented Kennedy from ever winning a majority at the Democratic Convention, and that Humphrey would have been the Democratic nominee even if Kennedy had lived. The journalist Richard Reeves and historian Michael Beschloss have both written that Humphrey was the likely nominee, and future Democratic National Committee chairman Larry O'Brien wrote in his memoirs that Kennedy's chances of winning the nomination had been slim, even after his win in California.
