Ranked choice voting is a method of casting ballots that lets you rank candidates in order of preference rather than picking just one. If your top choice is eliminated, your vote transfers to your next pick, and that process repeats until someone wins a majority. Two states and dozens of cities use some form of it today, while roughly 19 states have moved in the opposite direction and banned it outright.
How to Mark the Ballot
A ranked choice ballot looks like a grid. Candidate names run down the left, and columns across the top represent ranking positions: first choice, second choice, third choice, and so on. You fill in one bubble per column and one bubble per row, giving each candidate a unique rank.
Two mistakes trip voters up. The first is an overvote, which means filling in more than one bubble in the same column and giving two candidates the same rank. Jurisdictions handle this differently, but in most cases the overvoted ranking and any rankings after it are skipped or invalidated. The second is skipping a rank entirely, like jumping from first choice to third. Some jurisdictions ignore the gap and move to your next valid ranking; others stop counting the ballot after consecutive skipped ranks.
You don’t have to rank every candidate. If six people are running and you have opinions about three, ranking just those three is valid. The tradeoff: if all three get eliminated, your ballot stops counting in later rounds.
How Single-Winner Races Are Counted
Counting starts with everyone’s first-choice picks. If any candidate has more than half the votes right away, that candidate wins and the process is over. Most competitive races don’t end that quickly.
When nobody clears 50%, the candidate with the fewest first-choice votes is eliminated. Every ballot that ranked that candidate first is reassigned to whichever candidate the voter ranked next. Officials recount. If someone now has a majority, they win. If not, the next-lowest candidate is eliminated and the cycle repeats until someone crosses the threshold.
The whole thing happens in a single pass through the ballots rather than requiring voters to come back for a separate runoff weeks later. Tabulation software handles the round-by-round transfers in seconds and produces an audit trail showing exactly how votes moved at each stage.1Ranked Choice Voting Resource Center. Election
Why Results Take Longer
Election-night results in a ranked choice race usually show only first-choice totals, which can be misleading if the race goes to multiple rounds. Full round-by-round tabulation often doesn’t happen until all mail-in and provisional ballots have been processed. A plurality race can sometimes be called on election night from incomplete returns; a ranked choice race may need every ballot counted before officials can run the elimination rounds and declare a winner.
Tie-Breaking During Elimination
When two candidates are tied for the fewest votes and one has to be eliminated, the rules vary. Some jurisdictions look at which candidate had fewer votes in earlier rounds. Others allow simultaneous elimination of all tied candidates if their combined vote total is still lower than the next candidate above them. In rare cases where no tiebreaker method resolves the deadlock, a random drawing decides it. These procedures are written into the local election code before the race begins.
Exhausted Ballots and the Majority Question
A ballot becomes “exhausted” when every candidate a voter ranked has been eliminated but other candidates remain in the race. At that point, the ballot drops out of the count entirely. This is the natural consequence of not ranking every candidate.
It also drives one of the most common criticisms of the system: the winner’s “majority” is a majority of remaining active ballots, not necessarily a majority of all ballots originally cast. If enough ballots exhaust along the way, a candidate could win the final round with fewer total votes than half the people who showed up. Supporters argue this is no different from a low-turnout runoff election. Critics see it as overstating the winner’s mandate.
How Multi-Winner Races Work
When multiple seats need filling at once, ranked choice voting uses a method called the Single Transferable Vote. Instead of needing more than half the votes, candidates need to reach a lower threshold called the Droop quota, calculated by dividing the total number of valid ballots by the number of seats plus one, then adding one. In a race to fill three seats with 10,000 ballots cast, the quota would be 2,501.
Any candidate who hits the quota wins a seat immediately. Votes that a winning candidate received beyond the quota are surplus, and that surplus gets redistributed to voters’ next-ranked choices. The idea is that piling extra votes onto someone who already won wastes the influence of the voters who supported that candidate; transferring the surplus lets those voters help elect their next choice too.
Most modern implementations use fractional transfers, where each surplus ballot moves at a reduced value rather than pulling out random individual ballots. After surpluses are distributed, if seats remain unfilled, the candidate with the fewest votes is eliminated and those ballots transfer at full value to the next-ranked choice. The cycle continues until every seat is filled. The result is proportional representation: if 40% of voters share similar preferences, they elect roughly 40% of the available seats rather than being shut out entirely by a 60% majority.
Where Ranked Choice Voting Is Used
Alaska and Maine are the two states that use ranked choice voting for statewide and federal races, though they got there by different paths and apply it differently.
Alaska voters approved Ballot Measure 2 in 2020, creating a system that pairs an open top-four primary with a ranked choice general election for state and federal offices.2Alaska Division of Elections. Ballot Measure No. 2 – 19AKBE – Ballot Language Summary A repeal effort reached the ballot in November 2024 and narrowly failed, with 50.12% voting to keep the system and 49.88% voting to scrap it.
Maine’s framework lives in Title 21-A, §723-A of its election code and applies to federal races and certain state primaries.3Maine State Legislature. Maine Code Title 21-A 723-A – Determination of Winner in Election for an Office Elected by Ranked-Choice Voting Maine was the first state to use ranked choice voting for a congressional race, in 2018.
At the local level, several major cities use it. New York City adopted ranked choice voting through a 2019 charter amendment for primary and special elections covering mayor, public advocate, comptroller, borough president, and city council, with implementation beginning in 2021.4American Legal Publishing.

Where It Is Banned
While some jurisdictions have adopted ranked choice voting, a larger number of states have moved preemptively to prohibit it. As of early 2026, roughly 19 states have enacted laws or constitutional amendments banning ranked choice voting for any local, state, or federal election within their borders. Most of these bans passed between 2022 and 2026, with a concentrated burst of legislative activity in 2024 and 2025.
The bans are sweeping. They don’t just prevent statewide use; they block cities and counties from adopting ranked choice voting on their own. In a state with one of these laws on the books, a municipality that wanted to try ranked choice voting for city council races would be legally barred from doing so.
Court Challenges
Federal courts have consistently rejected constitutional challenges to ranked choice voting. The Ninth Circuit held in 2011 that ranking candidates does not dilute anyone’s vote and that any burden the system places on voters is minimal. Federal courts in Maine reached the same conclusion in multiple cases between 2018 and 2020, finding no violation of the Equal Protection Clause, the Due Process Clause, the First Amendment, or the Voting Rights Act.6Congress.gov. Ranked-Choice Voting – Legal Challenges and Considerations
State courts have been more mixed. The supreme courts of Alaska, Massachusetts, and Minnesota have all upheld ranked choice voting systems. In 2017, however, the Maine Supreme Judicial Court issued an advisory opinion that ranked choice voting conflicted with the state constitution’s requirement that candidates win by a plurality. That opinion didn’t strike down the law, but it prompted Maine to narrow its approach: the state now uses ranked choice voting for federal races, where the state constitutional provision doesn’t apply, and for primaries where the legislature determined the plurality requirement didn’t govern.
Nearly 40 state constitutions contain plurality-style language similar to Maine’s, which means future challenges could test whether that language actually prohibits ranked choice voting or simply describes a default the legislature can override. No federal court has found the system unconstitutional.
