An Al Jazeera explainer, with The Associated Press, sets out why the Mississippi and Alaska US Senate races remain undecided days after the 2026 midterms, in which Democrats regained control of both chambers of Congress. In Mississippi, where Scott Colom led Cindy Hyde-Smith by 1,138 votes, 10 days are allowed for provisional ballots and there is no automatic recount; Alaska's ranked-choice count, with Mary Peltola ahead of Dan Sullivan by 637 votes, is due on November 18, and the Justice Department, whose suit against certification was dismissed, has pledged to appeal.
