What Happens If: Election Contingencies, from a Candidate's Death to a Tie
Key takeaways
- Before Election Day, the national parties fill a vacancy on a presidential ticket, and states set deadlines for changing ballots.
- If no presidential candidate wins 270 electoral votes, the House chooses the President with one vote per state, and the Senate chooses the Vice President.
- A 269 to 269 electoral tie is possible and would go to the House.
- Ties in congressional and state races are broken under state law, sometimes by drawing lots.
- Congress sets Election Day, and no President can cancel or postpone a federal election. A 2022 law lets states extend voting only for catastrophic events under rules set in advance.
- Whatever happens, the Twentieth Amendment ends the President's term at noon on January 20, and succession law fills any gap.
Elections rarely go off script, but the law has answers, some clear and some untested, for what happens when they do. The rules come from the Twelfth and Twentieth Amendments, federal laws on Election Day and the electoral count, state election codes, and the rules of the political parties.
This guide, published on Election Day 2026, walks through the most common what-if questions, from a candidate's death to an Electoral College tie, and notes where the answers remain uncertain.
If no candidate wins a majority of the 538 electoral votes, the Twelfth Amendment sends the choice to the House, which picks among the top three with each state delegation casting one vote. A candidate needs 26 states. The Senate picks the Vice President from the top two. The House last chose a President in 1825, picking John Quincy Adams over Andrew Jackson, and the Senate last chose a Vice President in 1837. The House that decides is the one newly elected in November, which takes office January 3.
A 269 to 269 tie in the Electoral College would go to the House under the contingent election procedure. Ties in congressional and state legislative races are resolved under state law, which may call for a recount, a new election, a decision by the legislature, or drawing lots. In January 2018 a tied race for the Virginia House of Delegates, which decided control of the chamber, was settled by drawing a name from a bowl. In the Senate, a tie vote on legislation is broken by the Vice President.
If the House has not chosen a President by inauguration day, the Vice President-elect acts as President. If neither a President nor a Vice President has qualified, the Presidential Succession Act of 1947 makes the Speaker of the House acting President, followed by the President pro tempore of the Senate and the Cabinet. These provisions have never been used, and scholars have raised questions about them, including whether a Speaker would have to resign from Congress to serve.
For President, the national party committees fill a vacancy on the ticket under their own rules, as Democrats did when a vice presidential nominee withdrew in 1972 and after the President withdrew from the race in July 2024. Each state sets its own deadline for changing names on the ballot, and early and mail ballots already cast count for the ticket as listed, since voters are formally choosing electors. In congressional races, state law decides whether a party may name a replacement. When a dead candidate wins, as Mel Carnahan did in the 2000 Missouri Senate race, the seat is filled by appointment or special election.
No President can postpone or cancel a federal election. Congress set Election Day by law in 1845 and has never moved it, and elections went ahead during the Civil War and both world wars. States run the voting, and in 2001 New York postponed a local primary on the morning of the September 11 attacks. The Electoral Count Reform Act of 2022 allows a state to extend its voting period only for force majeure events that are extraordinary and catastrophic, under state laws enacted before Election Day. Even if no election were held, the Twentieth Amendment ends the President's term at noon on January 20.
Timing matters. If the winning candidate dies before the electors vote in mid-December, the party would recommend a replacement and electors, most of them bound by state law, would face a choice that state legislatures may address. In 1872 the losing candidate, Horace Greeley, died after the election, and his electors scattered their votes. Once Congress counts the votes on January 6, the winner is clearly the President-elect, and under the Twentieth Amendment the Vice President-elect becomes President if the President-elect dies. Scholars disagree about the weeks between the electors' votes and the count.
