The US midterm elections on Tuesday will decide control of Congress. Every House seat and 35 Senate seats are at stake, plus governor's races and local contests. Republicans' Senate majority could hinge on four states, and Trump is not on the ballot.

The US midterm elections on Tuesday will decide control of Congress. The balance of power in both the Senate and the House of Representatives is up for grabs, along with significant races for governor around the country. The midterms decide every House seat and 35 of the Senate's 100 seats, plus thousands of local and state officials and hundreds of ballot questions.

Republicans' Senate majority could hinge on Iowa, Kansas, Nebraska and Texas, while Democrats are defending seats in Michigan and Minnesota. Trump has asked voters to imagine he is on the ballot, though he is not on the ballot.
