2002 United States elections

Elections were held in the United States on November 5, 2002, in the middle of Republican President George W. Bush's first term. Republicans won unified control of Congress, picking up seats in both chambers of Congress, making Bush the first president since Franklin D. Roosevelt in 1934 to gain seats in both houses of Congress. In the gubernatorial elections, Democrats won a net gain of one seat. The elections were held just a little under fourteen months after the September 11 attacks. Thus, the elections were heavily overshadowed by the war on terror.

Republicans won a net gain of two seats in the Senate and so gained control of a chamber that they had lost in 2001 after Senator Jim Jeffords left the Republican Party. Republicans also picked up eight seats in the House of Representatives, thereby making this election cycle one of three midterm elections in which the incumbent president's party did not experience a net loss of seats in either chamber of Congress, the other two being 1934 and 1998. This is also the only election cycle in history where the incumbent president's party gained a chamber of Congress in a midterm election. Additionally, it was the most recent midterm in which the incumbent president's party did not lose control of at least one chamber and maintained a trifecta on the federal government.
