Hubert H. Humphrey, who served as vice president under Lyndon Johnson, emerged as the nominee for president following Johnson’s decision not to seek re-election. Humphrey’s campaign was hurt when anti-war protestors were beaten by Chicago police on live television outside of the Democratic National Convention. Humphrey was defeated by former Vice President Richard Nixon after only carrying 13 states in the presidential election. Humphrey went on to teach at Macalester College and the University Of Minnesota before returning to the U.S. Senate in 1971. He served in the Senate until his death of bladder cancer in 1978.
