Joseph Isadore "Joe" Lieberman (born February 24, 1942) is the junior United States Senator from Connecticut. First elected to the Senate in 1988, Lieberman was elected to a fourth term on November 7, 2006. In the 2000 United States presidential election, Lieberman was the Democratic nominee for Vice President, running with presidential nominee Al Gore, becoming the first Jewish candidate on a major American political party presidential ticket. The Gore–Lieberman ticket won the popular vote but ultimately failed to gain the electoral votes needed to win the controversial election. Lieberman ran for re-election to the U.S. Senate while he was also Gore's running mate, and he was re-elected by the voters of Connecticut. He was an unsuccessful candidate for the Democratic presidential nomination in the 2004 presidential election. Lieberman has been officially listed in Senate records for the 110th and 111th Congresses as an "Independent Democrat".
