Book excerpt: What if Kennedy were not killed that fateful day? What would the 1964 campaign have looked like? Would changes have been made to the ticket? How would Kennedy, in his second term, have approached Vietnam, civil rights, the Cold War? With Hoover as an enemy, would his indiscreet private life finally have become public? Would his health issues have become so severe as to literally cripple his presidency? And what small turns of fate in the days and years before Dallas might have kept him from ever reaching the White House in the first place? The answers Greenfield provides and the scenarios he develops are startlingly realistic, rich in detail, shocking in their projections, but always deeply, remarkably plausible. If Kennedy Lived is a tour de force of American history from one of the country’s most brilliant and illuminating political commentators.
