A faithless elector can withhold a vote from the presidential candidate they were expected to support, but that does not automatically change the winner. The effect depends on the election’s margin: a changed electoral vote could matter if it alters which candidate secures a majority, while in a decisive contest it may be only a protest.
The stakes turn on how Electoral College votes are counted and whether a state’s rules allow an elector’s vote to stand. A faithless elector’s choice can draw attention to the gap between voters’ preferences and the formal process of choosing a president—but its power is limited by the arithmetic of the result.
| Stage or rule | What it determines | Concrete detail |
|---|---|---|
| State popular vote | Which pledged electors are ordinarily appointed | State election result |
| Elector ballot | The vote cast in the Electoral College | President and vice president are voted on separately |
| State pledge law | Whether a defiant elector can be replaced or penalized | Rules vary by state |
| Presidential majority | Whether a candidate wins the Electoral College | 270 of 538 votes |
| Contingent election | How the president is chosen if no candidate has a majority | House votes by state delegation |

What is a faithless elector?
A faithless elector is a member of the Electoral College who casts an electoral vote for someone other than the candidate the elector was pledged to support. The change concerns that elector’s Electoral College vote; it does not rewrite the popular-vote count already recorded in the state.
What the vote changes—and what it does not
The Twelfth Amendment provides for electors to cast separate ballots for president and vice president. A faithless elector’s departure therefore applies to an Electoral College ballot, not directly to the state’s popular-vote tally.
A different electoral vote, by itself, does not establish that the state’s popular-vote result changed. The two are distinct records: the state’s popular-vote count and the elector’s ballot in the Electoral College.
How can an elector’s vote depart from a state’s result?
A state’s Electoral College result can depart from its popular-vote result when an appointed elector casts a ballot for a presidential ticket other than the one the state’s voters chose. Voters select among presidential tickets on Election Day in November; electors later cast the formal Electoral College ballots.
The two votes are related but are not the same tally: a state’s popular-vote winner ordinarily determines which pledged electors are appointed, while those electors’ subsequent ballots determine the Electoral College vote. A difference arises if an elector does not follow the state’s choice when casting that later ballot.
The Electoral College meets in December, after the November general election, to cast its ballots. That timing separates the voters’ state-level election result from the electors’ formal vote, leaving a later opportunity for an elector’s ballot to differ.
What can a faithless elector change in the outcome?
A faithless elector can change the Electoral College tally, but changes the winner only if the altered result removes the winning candidate’s majority or gives that majority to someone else. The threshold is 270 of the 538 electoral votes, provided all 538 electors are appointed.
The 270-vote threshold determines whether the presidential election is decided by the Electoral College or moves to the House of Representatives. If no candidate receives a majority of appointed electors’ votes, the Twelfth Amendment assigns the choice to the House, where each state delegation casts one vote.
What the vote does not change
A faithless elector’s ballot changes the electoral tally, not the state’s popular-vote result or the process by which that state selected its electors. Its effect therefore depends on the margin: a single changed vote may leave the winner’s majority intact, but it could matter if the tally is close enough to affect the 270-vote threshold.
Can a state punish or replace a faithless elector?
Yes. A state may enforce an elector’s pledge and, where its law allows, replace the elector before the vote is counted; the applicable state law determines the consequences. The rules vary by state, so there is no single nationwide penalty for casting a different vote.
What the Supreme Court decided
In Chiafalo v. Washington (2020), the U.S. Supreme Court upheld states’ authority to enforce elector pledges. The decision confirmed that states can use their own laws to address a faithless elector, including replacement where the law provides for it; it did not prescribe one uniform consequence for every state.
For an elector who breaks a pledge, the result therefore depends on the state’s rules: those rules govern both what happens to the elector and whether the ballot is counted or replaced. The court’s ruling establishes states’ authority, not an automatic national procedure, so the outcome cannot be determined from the Supreme Court decision alone.
When does a faithless vote not change the result?
A faithless Electoral College vote does not change the winner if the candidate it supports still finishes below the 270 votes needed for a majority. The decisive question is whether the changed tally takes a candidate to 270 or leaves the majority with someone else; a defection that does neither changes the count, not the outcome.
State law can also determine whether a defiant ballot counts as cast. Some states provide for replacing an elector who breaks a pledge or reject the ballot and enforce the elector’s commitment, so the recorded Electoral College vote may differ from the elector’s attempted vote. Rules vary by state: an elector’s action cannot be assumed to count everywhere, or to carry the same consequences.
Electoral votes are not popular votes
A change to the Electoral College tally does not revise a state’s popular-vote count. The popular vote records voters’ choices in the state; the Electoral College tally records the electors’ votes, subject to applicable state rules. Thus, a faithless elector may affect the electoral count without changing how many people voted for each candidate in that state.
What numbers define the Electoral College threshold?
The Electoral College threshold is 270 of 538 electoral votes: a presidential candidate needs a majority to win outright. The total consists of 435 electors corresponding to House seats, 100 corresponding to Senate seats, and three for the District of Columbia.
If no candidate reaches 270
The Twelfth Amendment provides a contingent-election process when no presidential candidate receives an electoral-vote majority. In that House process, each state delegation casts one vote, rather than each member of Congress voting separately.
The distinction is between the nationwide electoral-vote threshold and the state-based House procedure: 270 decides whether a candidate has a majority, while the Twelfth Amendment’s fallback assigns one vote to each state delegation. A faithless elector’s changed vote matters to this threshold if it affects whether a candidate reaches 270.
