Elections to the United States Senate will be held on November 6, 2018, with 33 of the 100 seats in the Senate being contested in regular elections whose winners will serve six-year terms from January 3, 2019, until January 3, 2025. Currently, Democrats are expected to have 23 seats up for election, additionally 2 independents who caucus with the Democrats are facing the end of their current term. Republicans are expected to have 9 seats up for election (including a special election in Alabama caused by the vacancy left by Senator Jeff Sessions, who had to resign his seat following his confirmation as United States Attorney General). The seats up for election in 2018 were last up for election in 2012, although some seats may have special elections if incumbents die or resign. Democrats gained 2 seats in the 2016 Senate elections.
