Election Day in the United States is the Tuesday following the second Monday of November. It is the day where polls open for the election of public and government officials. On even-numbered years, all members of the United States House of Representatives are placed on the ballot, either for reelection or replacement by a challenger. Also on even-numbered years, 1/3 of the U.S. Senators are placed on the ballot. On years divisible by four, the President of the United States is placed on the ballot, either to be reelected, beaten by a challenger, or, in cases where the president cannot (two terms being the maximum) or decides not to run again, entirely new candidates are placed on the ballot.
