We will update this article throughout the night as more data becomes available, so keep checking back. DW follows the Associated Press (AP) for when a seat is called for Republicans or Democrats. In the 2026 midterms , Americans voted on all 435 members of the House of Representatives and 35 members of the Senate. Before election night, Republicans held the majority in both Congress chambers, if only by a hair. Midterm elections are held every four years.
