Elections to the United States Senate was held on November 6, 2018, with 33 of the 100 seats in the Senate being contested in regular elections and one special election. The Republicans gained 11 seats, making it the biggest loss for the Democrats since the 1920's. The results were due to Hillary Clinton's low approval ratings and the dissatisfaction with the Democratic Party. The United States House of Representatives elections, 39 gubernatorial elections, and many other state and local elections were also held on this date.
