When Americans vote for President and Vice President of the United States, they are actually voting for presidential electors, known collectively as the Electoral College. It is these electors, chosen by the people, who elect the chief executive. The Constitution assigns each state a number of electors equal to the combined total of the state’s Senate and House of Representatives delegations; at present, the number of electors per state ranges from three (District of Columbia) to 55 (California), for a total of 538. To be elected President of the United States, a candidate needs a majority of 270 electoral votes.

How the Electoral College Works 

Aside from Members of Congress and people holding offices of “Trust or Profit” under the Constitution, anyone may serve as an elector.

In each presidential election year, a group of candidates for elector is nominated by political parties and other groupings in each state, usually at a state party convention or by the party-state committee. It is these elector-candidates, rather than the presidential and vice-presidential nominees, for whom the people vote in the November election, which is held on Tuesday after the first Monday in November. In most states, voters cast a single vote for the slate of electors pledged to the party presidential and vice-presidential candidates of their choice. The slate winning the most popular votes is elected. This is known as the winner take all system, or general ticket system.

Electors assemble in their respective states on Monday after the second Wednesday in December. They are pledged and expected, but not required, to vote for the candidates they represent. Separate ballots are cast for President and Vice President, after which the Electoral College ceases to exist for another four years. The electoral vote results are counted and certified by a joint session of Congress, held on January 6 of the year succeeding the election. A majority of electoral votes (currently 270 of 538) is required to win. If no candidate receives a majority, then the President is elected by the House of Representatives and the Vice President is elected by the Senate, a process known as contingent election.

The Electoral College in the U.S. Constitution

The original purpose of the Electoral College was to reconcile differing state and federal interests, provide a degree of popular participation in the election, give the less populous states some additional leverage in the process by providing “senatorial” electors, preserve the presidency as independent of Congress and generally insulate the election process from political manipulation.

The Constitutional Convention of 1787 considered several methods of electing the President, including selection by Congress, by the governors of the states, by the state legislatures, by a special group of Members of Congress chosen by lot and by direct popular election. Late in the convention, the matter was referred to the Committee of Eleven on Postponed Matters, which devised the Electoral College system in its original form. This plan, which met with widespread approval by the delegates, was incorporated into the final document with only minor changes.

The Constitution gave each state a number of electors equal to the combined total of its membership in the Senate (two to each state, the “senatorial” electors) and its delegation in the House of Representatives (currently ranging from one to 52 Members). The electors are chosen by the states “in such Manner as the Legislature thereof may direct” (U.S. Constitution, Article II, section 1).

Qualifications for the office are broad: the only people prohibited from serving as electors are Senators, Representatives and people “holding an Office of Trust or Profit under the United States.”

In order to forestall partisan intrigue and manipulation, the electors assemble in their respective states and cast their ballots as state units, rather than meet at a central location. At least one of the candidates for whom the electors vote must be an inhabitant of another state. A majority of electoral votes is necessary to elect, a requirement intended to insure broad acceptance of a winning candidate, while election by the House was provided as a default method in the event of Electoral College deadlock. Finally, Congress was empowered to set nationwide dates for choice and meeting of electors.

All the foregoing structural elements of the Electoral College system remain in effect currently. The original method of electing the President and Vice President, however, proved unworkable and was replaced by the 12th Amendment, ratified in 1804. Under the original system, each elector cast two votes for President (for different candidates), and no vote for Vice President. The votes were counted and the candidate receiving the most votes, provided it was a majority of the number of electors, was elected President, and the runner-up became Vice President. The 12th Amendment replaced this system with separate ballots for President and Vice President, with electors casting a single vote for each office.

The Electoral College Today

Notwithstanding the founders’ efforts, the Electoral College system almost never functioned as they intended, but, as with so many constitutional provisions, the document prescribed only the system’s basic elements, leaving ample room for development. As the republic evolved, so did the Electoral College system, and, by the late 19th century, the following range of constitutional, legal and political elements were in place on both a state and federal level:

Allocation of Electors and Electoral Votes

The Constitution gives each state a number of electors equal to the combined total of its Senate membership (two for each state) and House of Representatives delegation (currently ranging from one to 55, depending on population). The 23rd Amendment provides an additional three electors to the District of Columbia. The number of electoral votes per state thus currently ranges from three (for seven states and D.C.) to 55 for California, the most populous state.

The total number of electors each state gets are adjusted following each decennial census in a process called reapportionment, which reallocates the number of Members of the House of Representatives to reflect changing rates of population growth (or decline) among the states. Thus, a state may gain or lose electors following reapportionment, but it always retains its two “senatorial” electors, and at least one more reflecting its House delegation. Popular Election of Electors

Today, all presidential electors are chosen by voters, but in the early republic, more than half the states chose electors in their legislatures, thus eliminating any direct involvement by the voting public in the election. This practice changed rapidly after the turn of the nineteenth century, however, as the right to vote was extended to an ever-wider segment of the population. As the electorate continued to expand, so did the number of persons able to vote for presidential electors: Its present limit is all eligible citizens age 18 or older. The tradition that the voters choose the presidential electors thus became an early and permanent feature of the Electoral College system, and, while it should be noted that states still theoretically retain the constitutional right to choose some other method, this is extremely unlikely. 

The existence of the presidential electors and the duties of the Electoral College are so little noted in contemporary society that most American voters believe that they are voting directly for a President and Vice President on Election Day. Although candidates for elector may be well-known persons, such as governors, state legislators or other state and local officials, they generally do not receive public recognition as electors. In fact, in most states, the names of individual electors do not appear anywhere on the ballot; instead, only those of the various candidates for President and Vice President appear, usually prefaced by the words “electors for.” Moreover, electoral votes are commonly referred to as having “been awarded” to the winning candidate, as if no human beings were involved in the process.

The Electors: Ratifying the Voter’s Choice

Presidential electors in contemporary elections are expected, and in many cases pledged, to vote for the candidates of the party that nominated them. While there is evidence that the founders assumed the electors would be independent actors, weighing the merits of competing presidential candidates, they have been regarded as agents of the public will since the first decade under the Constitution. They are expected to vote for the presidential and vice-presidential candidates of the party that nominated them. 

Notwithstanding this expectation, individual electors have sometimes not honored their commitment, voting for a different candidate or candidates than the ones to whom they were pledged. They are known as “faithless” or “unfaithful” electors. In fact, the balance of opinion by constitutional scholars is that, once electors have been chosen, they remain constitutionally free agents, able to vote for any candidate who meets the requirements for President and Vice President. Faithless electors have, however, been few in number (in the 20th century, there was one each in 1948, 1956, 1960, 1968, 1972, 1976, 1988, and 2000), and have never influenced the outcome of a presidential election.

How the Electoral College Works in Each State 

Nomination of elector-candidates is another of the many aspects of this system left to state and political party preferences. Most states prescribe one of two methods: 34 states require that candidates for the office of presidential elector be nominated by state party conventions, while a further ten mandate nomination by the state party’s central committee. The remaining states use a variety of methods, including nomination by the governor (on the recommendation of party committees), by primary election, and by the party’s presidential nominee.

Joint Tickets: One Vote for President and Vice President

General election ballots, which are regulated by state election laws and authorities, offer voters joint candidacies for President and Vice President for each political party or other groups. Thus, voters cast a single vote for electors pledged to the joint ticket of the party they represent. They cannot effectively vote for a president from one party and a vice president from another unless their state provides for write-in votes.

General Election Day

Elections for all federal elected officials are held on the Tuesday after the first Monday in November in even-numbered years and presidential elections are held in every year divisible by four. Congress selected this day in 1845; previously, states held elections on different days between September and November, a practice that sometimes led to multiple voting across state lines and other fraudulent practices. By tradition, November was chosen because the harvest was in and farmers were able to take the time needed to vote. Tuesday was selected because it gave a full day’s travel between Sunday, which was widely observed as a strict day of rest, and Election Day. Travel was also easier throughout the north during November, before winter had set in.

The Electors Convene

The 12th Amendment requires electors to meet “in their respective states…” This provision was intended to deter manipulation of the election by having the state electoral colleges meet simultaneously, but keeping them separate. Congress sets the date on which the electors meet, currently the first Monday after the second Wednesday in December. The electors almost always meet in the state capital, usually in the capitol building or state house itself. They vote “by ballot” separately for President and Vice President (at least one of the candidates must be from another state). The results are then endorsed, and copies are sent to the Vice President (in his capacity as President of the Senate); the secretary of state of their state; the Archivist of the United States; and the judge of the federal district court of the district in which the electors met. Having performed their constitutional duty, the electors adjourn, and the Electoral College ceases to exist until the next presidential election.

Congress Counts and Certifies the Vote

The final step in the presidential election process (aside from the presidential inaugural on January 20) is the counting and certification of the electoral votes by Congress. The House of Representatives and Senate meet in joint session in the House chamber on January 6 of the year following the presidential election at 1:00 pm. The Vice President, who presides in his capacity as President of the Senate, opens the electoral vote certificates from each state in alphabetical order. He then passes the certificates to four tellers (vote counters), two appointed by each house, who announce the results. The votes are then counted and the results are announced by the Vice President. The candidate who receives a majority of electoral votes (currently 270 of 538) is declared the winner by the Vice President, an action that constitutes “a sufficient declaration of the persons, if any, elected President and Vice President of the States.”
