You can spend an entire election cycle hearing that “the Electoral College picks the president,” only to discover that the Constitution quietly wrote a backup plan for when the Electoral College cannot do its job.
That backup plan is the contingent election. It is rare, procedural, and deeply political in a way that feels almost antique. It is also absolutely still the law.
This article walks through what happens when nobody reaches 270 electoral votes, including the famous 269–269 tie, and explains the distinct roles the House and Senate play under the Constitution.

The key rule: 270 is not a suggestion
Under modern practice, a presidential candidate needs a majority of the whole number of appointed electors to win. With 538 electors today, that majority is 270.
If no candidate wins that majority, the Constitution does not say “recount.” It does not say “revote.” It says: the House chooses the president and the Senate chooses the vice president, using specific constitutional rules.
Two common deadlock scenarios
- 269–269 tie: two candidates split the Electoral College evenly, so neither has a majority.
- No majority with more than two candidates: a third-party or faithless-elector outcome keeps everyone below 270, even if one candidate leads (for example, 268–267–3).
Both situations trigger the same constitutional mechanism: the contingent election.
Where the Constitution assigns the job
The rules for a contingent election live in the 12th Amendment. It replaced the original Electoral College mechanics in Article II after the election of 1800 exposed how fragile the first design was.
In plain terms, the 12th Amendment does three things that matter here:
- It requires electors to cast separate votes for president and vice president.
- If no one wins a majority for president, the House of Representatives chooses the president from the top three electoral vote recipients.
- If no one wins a majority for vice president, the Senate chooses the vice president from the top two electoral vote recipients.
Those are not symbolic roles. They are decisive.
Step by step: what happens when no one gets 270
Step 1: Electors vote, but the math fails
Electors meet in their states and cast ballots for president and vice president. Those votes are sent to Congress.
If the electoral vote totals produce no majority for president, the process moves toward a contingent election once the votes are opened and counted in Congress.
Step 2: Congress counts the votes in a joint session
Congress meets in a joint session to open the states’ electoral certificates and count the votes. This is the part most people picture as “certification.”
Under the modern statutory process, Congress follows the Electoral Count Act framework as amended by the Electoral Count Reform Act of 2022, including procedures for objections and for handling competing claims about electoral certificates within the limits the statute sets.
But here is the pivot point: even if everything is counted cleanly and peacefully, a deadlock still produces a constitutional problem. Counting does not create a majority that does not exist.
One timing detail that matters: the contingent election is conducted by the newly elected Congress (the new House is seated on January 3), not the outgoing one.
Step 3: The House chooses the president, but by state delegation
If no one has an Electoral College majority for president, the 12th Amendment says the House must choose the president from the top three electoral vote recipients.
This is the part that surprises people: the House does not vote one member, one vote.
- Each state delegation gets one vote.
- A candidate must win a majority of the states to become president. With 50 states, that means 26 state votes.
- The District of Columbia does not vote in a contingent election because the 12th Amendment assigns the vote to state delegations in the House. (DC’s three electors matter in the Electoral College. They do not become a “state delegation” vote in the House.)
So California gets one vote. Wyoming gets one vote. The size of the state does not change the value of the delegation’s ballot.
How the House state vote works
The House conducts the contingent election as a vote of state delegations. That means:
- Representatives from each state caucus internally to decide how their state will vote.
- If a state delegation is tied, it may be unable to cast a vote at all.
- In practice and by precedent, the House continues balloting until someone wins a majority of states.
A quick mini-example: if one candidate wins 25 state delegations and the other wins 24, with one state delegation deadlocked and unable to vote, nobody has the required 26. The House keeps going until that changes.
Who controls a state’s one vote?
Control comes down to which party has more members in that state’s House delegation. For example, if a state has 10 representatives and Party A holds 6, Party A likely controls the state’s single contingent-election vote.
This is why a contingent election can produce an outcome that feels disconnected from the national popular vote and even from the raw national House seat totals. The unit that matters is the state delegation majority, not the national headcount.
Quorum and thresholds
The 12th Amendment requires that a contingent election for president have:
- A quorum consisting of members from two-thirds of the states.
- A winning majority consisting of a majority of all the states.
Those rules are meant to prevent a small slice of the House from selecting a president on behalf of the entire country.
What about ties for third place?
Most of the time, “top three” is straightforward. In an edge case where candidates tie around the third-place cutoff, the constitutional text limits the field to persons “not exceeding three,” but a tie can complicate who qualifies. If that situation ever arose, it would likely trigger intense parliamentary and legal wrangling before the House could vote.
The Senate chooses the vice president
For vice president, the Constitution uses a different body and a different voting rule:
- If no vice presidential candidate wins a majority of electoral votes, the Senate chooses the vice president.
- The Senate chooses from the top two vice presidential electoral vote recipients.
- Each senator gets one vote.
- A candidate must win a majority of the whole Senate to become vice president. Today, that means 51 of 100, not merely a majority of those present.
- The 12th Amendment also requires a quorum of two-thirds of the whole number of Senators to conduct this vote (currently 67).
In other words, the vice presidency is chosen by the Senate the normal way the Senate decides things, with one vote per senator and a majority of the full membership, rather than by state units.
As with the House, a rare tie at the cutoff could create ambiguity. The Constitution says the Senate chooses “from the two highest numbers,” so a tie for second could complicate who counts as “the two.”
What if the House cannot decide by Inauguration Day?
The Constitution anticipates the possibility of delay. The 20th Amendment (Section 3) addresses what happens at the start of the term if a president has not been chosen.
In practice, that means:
- If the House has not chosen a president by the time the term begins, but the Senate has selected a vice president, the vice president-elect can serve as acting president until the House chooses.
- If neither a President-elect nor a Vice President-elect has been determined by noon on January 20, the situation shifts to statutory succession rules, primarily the Presidential Succession Act. Under that law, the Speaker of the House is next in line to act as president (if qualified and after resigning from the House and the speakership).
Even in a double-deadlock, the constitutional core remains: once the House is able to do so, it is still the body tasked by the 12th Amendment with choosing the president from the eligible electoral vote recipients, while an acting president may serve in the meantime.
How this differs from normal certification
Most years, the process is linear:
- Electors vote.
- Congress counts.
- Someone has 270 or more.
- The winners are declared.
A contingent election is different because it is not mainly about counting disputes. It is about the absence of a constitutional majority.
Count disputes vs. contingent election
These are often confused, especially after high-profile controversies about certification.
- Electoral Count Act style disputes ask: which electoral votes are valid, and what procedures govern objections and competing certificates under federal law (including the 2022 reforms)?
- Contingent election asks: after the valid votes are counted, did anyone actually win a majority? If not, the Constitution assigns the final selection to the House and Senate.
You can have one without the other. A contingent election can happen even if every state’s electoral votes are undisputed. And a certification dispute can happen even when someone clearly has 270.
Has this actually happened?
Yes, but not often. The contingent election procedure is part of our constitutional history, not a speculative fantasy.
- 1801: The House chose Thomas Jefferson after an Electoral College tie under the original rules. This crisis led to the 12th Amendment.
- 1825: The House chose John Quincy Adams after no candidate won an Electoral College majority in a four-way race.
Since then, the system has come close at times, but contingent elections remain exceptional. Exceptional does not mean impossible.
Plain-language recap
- If nobody wins 270 electoral votes, the election is not “thrown into chaos.” It is thrown into a process the Constitution already wrote down.
- The House chooses the president from the top three, but each state gets one vote.
- The Senate chooses the vice president from the top two, with one vote per senator, and a majority of the full Senate required.
- This is separate from the normal certification process. It is not primarily about objections. It is about the lack of a majority.
FAQ: common misconceptions
Does the House vote like it does on bills, with 435 individual votes?
No. In a contingent election for president, the House votes by state delegations. Each state has one vote, regardless of population.
Does a 269–269 tie automatically go to the Supreme Court?
No. A tie is a no-majority outcome. The Constitution routes it to the contingent election process in the 12th Amendment. Courts may get involved only if there is a separate legal dispute about ballots, electors, or counting rules.
Does the vice president break the tie in a contingent election?
Not for choosing the president. The vice president has no tie-breaking role in the House’s state-delegation vote. The vice president can break ties in the Senate on ordinary Senate business, but the Senate’s constitutional role here is to choose the vice president from the top two.
Does the District of Columbia get a vote in the House contingent election?
No. DC has electoral votes under the 23rd Amendment, but the contingent election vote in the House is conducted by states. DC is not a state and has no state delegation.
Is a contingent election the same thing as a recount or revote?
No. A contingent election is not a redo of the general election. It is a constitutionally defined selection by Congress after the Electoral College produces no majority.
Can the House pick someone who was not on the ballot?
No. The House must choose from the top three electoral vote recipients for president. The Senate must choose from the top two for vice president.
