On Nov. 5, a number of states will elect U.S. senators for new six-year terms starting in 2025. The winners will determine which party has a Senate majority for the next two years and so will be critical to the new president—especially for Cabinet and judicial nominations, each of which must be confirmed by the Senate.
Beyond nominations, the Senate majority will affect the productivity of Congress and influence the kind of legislation it passes, which makes these elections determinative of national politics.
