The 1930 United States elections were held on November 4, 1930, in the middle of Republican President Herbert Hoover's term. Taking place shortly after the start of the Great Depression, the Republican Party suffered substantial losses. The election was the last of the Fourth Party System, and marked the first time since 1918 that Democrats controlled either chamber of Congress. The Republicans also lost eight seats to the Democrats in the U.S. Senate, but were able to maintain control with Republican Vice President Charles Curtis casting the tie breaking vote.
