WASHINGTON (AP) — If you’re tuning in now to Election Day in the U.S., voting in the midterm election ends when polls close on Tuesday. Millions of Americans have already cast ballots either early in person or by mail, with millions more set to vote in person at their polling places. Every U.S. House seat is up for election this year, along with about a third of the U.S. Senate. On the line is control of both houses of Congress, currently under Democratic leadership. Voters are also electing governors in most of the states this year. They’ll be in office in 2024 when the next presidential election happens and could affect election laws or vote certifications.
