A total of 470 seats in the U.S. Congress (35 Senate seats and all 435 House seats) are up for election on November 8. The seats of 5 of the 6 non-voting members of the U.S. House are up for election as well, writes ballotpedia.org.

Two special elections for the U.S. Senate are scheduled for tomorrow. One special election will be held to fill the final four years of Sen. Jim Inhofe’s six-year term that began in 2021. Inhofe announced his resignation effective January 3, 2023. The other special election will be held to fill the final weeks of the six-year term that Kamala Harris was elected to in 2016. That U.S. Senate seat is also up for regular election in 2022, for a total of 35 individual Senate seats up. Special elections for the U.S. House will be held throughout the year to fill vacancies that occur in the 117th Congress.

The 2022 election will be the first to take place following apportionment and redistricting after the 2020 census. As a result of apportionment, six states (Texas, Colorado, Florida, Montana, North Carolina, and Oregon) gained seats in the U.S. House, and seven states (California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia) lost seats.
