The United States midterm elections will be held in six weeks, on November 8. All 435 House of Representatives seats are up for election, as well as 35 of the 100 senators. Democrats won the House by 222-213 in 2020, and hold the Senate on a 50-50 tie with Vice President Kamala Harris’ casting vote.
Currently the FiveThirtyEight forecasts give Democrats a 68% chance to hold the Senate, but Republicans have a 69% chance to gain control of the House of Representatives.
That means there’s about a 31% chance of either Republicans or Democrats sweeping both chambers of Congress, and a 38% chance of Republicans winning the House while Democrats retain the Senate.
