George Stanley McGovern was an American politician, historian, U.S. representative, U.S. senator, and the Democratic Party presidential nominee in the 1972 presidential election. McGovern grew up in Mitchell, South Dakota, where he was a renowned debater. He became most known for his outspoken opposition to the growing U.S. involvement in the Vietnam War. He staged a brief nomination run in the 1968 presidential election as a stand-in for the assassinated Robert F. Kennedy. McGovern's long-shot, grassroots-based 1972 presidential campaign found triumph in gaining the Democratic nomination but left the party badly split ideologically, and the failed vice-presidential pick of Thomas Eagleton undermined McGovern's credibility. In the general election McGovern lost to incumbent Richard Nixon in one of the biggest landslides in U.S. electoral history. Though re-elected to the Senate in 1968 and 1974, McGovern was defeated in his bid for a fourth term in 1980.
