How the 2026 US midterm elections unfolded

On 3 November 2026 US voters elect all 435 members of the House of Representatives, 35 senators and 36 state governors. The run-up was shaped by an unusual round of mid-decade congressional redistricting, a Supreme Court ruling narrowing the Voting Rights Act, and court fights over voting rules. In Alaska a federal lawsuit filed by the Justice Department seeks to hold up certification of the Senate result in some circumstances.
