Through the 2020 election, there have been a total of 165 instances of faithlessness. They have never swung an election, and nearly all have voted for third party candidates or non-candidates, as opposed to switching their support to a major opposing candidate. There were 63 faithless electors in 1872 when Horace Greeley died between Election Day and when the Electoral College convened, but Ulysses S. Grant had already clinched enough to win reelection. During the 1836 election, Virginia's entire 23-man electoral delegation faithlessly abstained from voting for victorious Democratic vice presidential nominee Richard M. Johnson. The loss of Virginia's support caused Johnson to fall one electoral vote short of a majority, causing the vice-presidential race to be thrown into the U.S. Senate under a contingent election. The presidential election itself was not in dispute because Virginia's electors voted for Democratic presidential nominee Martin Van Buren as pledged. The Senate elected Johnson as vice president anyway after a party-line vote.
