The 1968 United States presidential election was the 46th quadrennial presidential election, held on Tuesday, November 5, 1968. The Republican nominee, former vice president Richard Nixon, defeated both the Democratic nominee, incumbent vice president Hubert Humphrey, and the American Independent Party nominee, former Alabama governor George Wallace. This was the last election until 1988 in which the incumbent president was not on the ballot. Incumbent president Lyndon B. Johnson had been the early front-runner for the Democratic Party’s nomination, but he withdrew from the race after only narrowly winning the New Hampshire primary. Eugene McCarthy, Robert F. Kennedy and Humphrey emerged as the three major candidates in the Democratic primaries until Kennedy was assassinated. His death after midnight on June 6, 1968, continued a streak of high-profile assassinations in the 1960s.
