Title: 2021 United States Electoral College vote count
Content:  The United States Electoral College is the group of presidential electors required by the Constitution to form every four years for the sole purpose of electing the president and vice president. Each state appoints electors according to its legislature, equal in number to its congressional delegation (senators and representatives). Federal office holders cannot be electors. Of the current 538 electors, an absolute majority of 270 or more electoral votes is required to elect the president and vice president. If no candidate achieves an absolute majority there, a contingent election is held by the United States House of Representatives to elect the president, and by the United States Senate 
Title: List of United States presidential elections by Electoral College margin
Content:  In United States presidential elections, citizens who are registered to vote cast ballots for members of the Electoral College, who then cast electoral votes for president and vice president. In order to be elected to office, a candidate must win an absolute majority of electoral votes. Since the Twenty-third Amendment gave citizens residing in the District of Columbia the right to vote, this has meant winning at least 270 of the 538 electoral votes. Since the Twelfth Amendment in 1804, electors have cast separate votes for the president and vice president. Previously, each elector cast two votes for president, and the winner and runner-up became president and vice president, respectively.

Title: United States presidential election
Content:  The election of the president and the vice president of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the fifty U.S. states or in Washington, D.C., cast ballots not directly for those offices, but instead for members of the Electoral College. These electors then cast direct votes, known as electoral votes, for president, and for vice president. The candidate who receives an absolute majority of electoral votes (at least 270 out of 538, since the Twenty-Third Amendment granted voting rights to citizens of D.C.) is then elected to that office. If no candidate receives an absolute majority of

Content:  president and vice president are inaugurated on January 20. Since 1964, there have been 538 electors. States select 535 of the electors, this number matches the aggregate total of their congressional delegations. The additional three electors come from the Twenty-third Amendment, ratified in 1961, providing that the district established pursuant to Article I, Section 8, Clause 17 as the seat of the federal government (namely, Washington, D.C.) is entitled to the same number of electors as the least populous state. In practice, that results in Washington D.C. being entitled to 3 electors. U.S. territories (both modern-day territories like Puerto Rico and historical territories like the Dakota Territory) have never been entitled to any electors in the Electoral College.

The Electoral College and its procedure are established in the U.S. Constitution by Article II, Section 1, Clauses 2 and 4; and the Twelfth Amendment (which replaced Clause3 after its ratification in 1804). Under Clause2, each state casts as many electoral votes as the total number of its Senators and Representatives in Congress, while (per the Twenty-third Amendment, ratified in 1961) Washington, D.C., casts the same number of electoral votes as the least-represented state, which is three. Also under Clause2, the 
Title: United States presidential election
Content:  Article Two of the Constitution originally established the method of presidential elections, including the creation of the Electoral College, the result of a compromise between those constitutional framers who wanted the Congress to choose the president, and those who preferred a national popular vote. As set forth in Article Two, each state is allocated a number of electors equal to the number of its delegates in both houses of Congress, combined. In 1961, the ratification of the Twenty-Third Amendment granted a number of electors to the District of Columbia, an amount equal to the number of electors allocated to the least populous state. However, U.S. territories are not allocated electors, and therefore are not represented in the Electoral College.
Title: Contingent election
Content:  In the United States, the president and vice president are indirectly elected by the Electoral College, which, since ratification of the 23rd Amendment in 1961, consists of presidential electors from the 50 states and the District of Columbia. The current total of 538 electors that make up the Electoral College are directly elected by their respective states. Since the election of 1824, a majority of the states have chosen their electors on a statewide winner-take-all basis, based on the statewide popular vote on Election Day. Maine and Nebraska are the only two current exceptions, as both states use the congressional district method. Although ballots list the names of the presidential and vice presidential candidates (who run on a ticket), voters actually choose electors when they vote for president

However, there are several states where this is not required by law. In the United States, 270 electoral votes of the 538 electors are currently required to win the presidential election. If no candidate receives the required 270 electoral votes, the lower chamber of the United States' Congress, the House of Representatives, chooses the President, with each state delegation receiving one vote in this election by the Legislature. The Senate
