Overall
Electoral College: 538 electors; you need 270 (50%+) to win presidential election; Source: USAGov
each state gets as many electors as it has members of Congress (House + Senate);
after you cast your ballot for president, your vote goes to a statewide tally: in 48 states and Washington D.C. the winner gets all the electoral votes for that state (exception: Maine and Nebraska assign their electors using a proportional system)
5 times the candidate has won the Electoral College and presidency despite losing the popular vote:
2016
2000
three times in the 1800s
if no candidate receives the majority of electoral votes: the vote goes to the House of Representatives - has happened twice: 1800 and 1824 elections
“faithless electors” are rogue Electoral College delegates who refuse to cast their votes for the presidential candidate they were pledged to support; since the founding of the Electoral College, there have been 167 faithless electors (67 cast their votes for a different candidate on their own); there were 10 faithless electors in 2016 who voted, or tried to vote, for someone other than Trump or Hillary Clinton; 32 states have some sort of faithless elector law, but only 15 of those remove, penalize, or simply cancel the votes of the errant electors: Michigan, Colorado, Utah, Arizona, Indiana, Minnesota, Montana, Nebraska, Nevada, Washington, California, New Mexico, South Carolina, Oklahoma, and North Carolina; Source: NPR and CBS News and Bloomberg
538 electors in the U.S. Electoral College, whom directly vote for the president; they are apportioned by population to the 50 states (one for each member of their congressional delegation, with the District of Columbia having 3 votes); the winner is the first candidate to receive a minimum of 270 electoral college votes (it takes 270 electoral votes to win the presidency); Maine and Nebraska are the only 2 states in the United States to offer proportional representation in the electoral votes that they award to presidential candidates, as opposed to the “winner-take-all” system that other states have; Source: We the People and White House and NBC News and AP News and Fortune
the Electoral process in the United States consists of: (1) Primary Elections: select each party’s candidates for the general election – Closed Primary: only registered members of a specific political party can vote for that party’s candidates and Open Primary: all registered voters can vote for a party’s candidates; (2) General Elections: select the public official for a particular government position; (3) Ballot Initiatives: laws or policy changes that are proposed by citizens or interest groups and decided through popular vote; (4) Referendum: referring proposed laws that were passed by a legislature to an electorate vote; and (5) Recall Elections: removing state public officials from office during their terms through popular vote; Reference: We the People by Benjamin Ginsberg, Theodore J. Lowi, Margaret Weir, Caroline Tolbert, and Robert J. Spitzer (2014)
when Americans cast their ballots for the U.S. president, they are actually voting for a representative of that candidate’s party known as an elector; there are 538 electors who then vote for the president on behalf of the people in their state; the process of nominating electors varies by state and by party but it is generally done 1 of 2 ways: ahead of the election, political parties either choose electors at their national conventions, or they are voted for by the party’s central committee; Source: The Guardian
Electoral College: 538 electors decide who will be elected U.S. president and vice president; each state gets as many electors as it has members of Congress (House and Senate); each state’s political parties choose their own slate of potential electors; who is chosen to be an elector, how, and when varies by state; after you cast your ballot for president, your vote goes to a statewide tally: in 48 states and Washington D.C. the winner gets all the electoral votes for that state (exception: Maine and Nebraska assign their electors using a proportional system); a candidate needs the vote of at least 270 electors (more than 50% of all electors) to win the presidential election; in most cases, a projected winner is announced on election night in November after you vote but the actual Electoral College vote takes place in mid-December when the electors meet in their states; while the Constitution does not require electors to vote for the candidate chosen by their state’s popular vote, some states do; the rare elector who votes for someone else may be fined, disqualified, and replaced by a substitute elector, or potentially even prosecuted by their state; 5 times the candidate has won the Electoral College and presidency despite losing the popular vote: 2016, 2000, and three times in the 1800s; if no candidate receives the majoreity of electoral votes: the vote goes to the House of Representatives (has happened twice: 1800 and 1824 elections); Source: USAGov
the Electoral College system dictates a presidential election’s winner; the system requires candidates to win uniform blocks of electoral votes from states; there are 538 electors; the Electoral College is a mostly winner-take-all system that delivers a set number of electoral votes per state to the winner of the popular vote there; that number is based on a state’s headcount in Congress – the minimum is three (as in Alaska and Wyoming, for example) and the maximum is 55 (California); there are 538 in total (and 270 are needed to win); the winner of the popular vote has lost the election 5 times (including twice since the year 2000); candidates are compelled by the system to neglect the parts of the country where most people live; Maine and Nebraska are unique in that each can split their electoral votes; the states that have awarded their electoral votes to candidates from different parties (rather than a single party) in the past 3 U.S. presidential elections are: Iowa, Wisconsin, Michigan, Indiana, Ohio, Pennsylvania, North Carolina, and Florida; Source: World Economic Forum
