How ranked choice voting works: A guide ahead of New York City's primary
When New Yorkers fill out ballots in Tuesday's mayoral primary, they'll be able to choose more than just one candidate. They can pick a second choice. And a third. And a fourth. And a fifth.
It's part of a process called ranked choice voting, a system that lets voters rank candidates in order of preference rather than pick just one.
Supporters of the system say ranked choice voting builds consensus, promotes positive campaigning and lets voters express a fuller range of opinions. Opponents argue it's overly complicated and can lead to ballots' being thrown out.
Here's what you need to know about ranked choice voting.
How does ranked choice voting work?
Ranked choice voting is a method of voting in which people rank candidates in order of preference. The number of candidates voters can rank depends on the specific rules in an area. In New York City, voters can rank up to five in one race.
Voters don't have to fill their ballots, though. A voter whose heart is set on only one candidate can just pick one. But if that candidate doesn't get the most votes, that voter won't have a say in later rounds of counting.
After the votes are tabulated, the last-place candidate is eliminated. Ballots from voters who supported that candidate then have the next choice counted. If no candidate has hit 50%, then counting continues, eliminating another last-place candidate and counting the next-ranked choices on all those ballots in the next round.
The process continues until a candidate reaches majority support and wins.
How long does it take to count the votes?
It depends on where the election is. In Maine, for example, the ranked choice tabulation in one of the state's congressional districts was conducted on Nov. 15 last year, 10 days after Election Day.
In New York City, the Board of Elections will post unofficial results from the first round of votes on election night.
Preliminary elimination rounds will be tabulated a week later, and officials will post an unofficial report, according to the elections board. The results could still change as mail and affidavit ballots are processed.
It can take longer to project winners in ranked choice votes, because election authorities need to have every ballot counted before they know in what order to eliminate last-place finishers. And as we know from recent elections, it can take some time to process and count mail-in ballots, provisional votes and others.
Why use ranked choice voting?
Supporters argue that ranked choice voting strengthens democracy by promoting positive campaigning and coalition-building, since people choose more than one candidate.
Advocates also say the system encourages politicians to find middle ground, which could help reduce the number of lawmakers on the ideological fringe.
'With RCV, candidates run more positive campaigns — or even 'cross-endorse' one another. Instead of worrying about 'wasting' their vote or picking the lesser of two evils, voters can rank their honest preferences. RCV rewards candidates who can build a majority coalition,' Deb Otis, the director of research and policy for the election reform group FairVote, said in a statement.
In New York, mayoral contender Zohran Mamdani, for example, has announced cross-endorsements with fellow contenders Michael Blake and Brad Lander in an effort to consolidate support.
The system is also called instant runoff voting, since it replaces the need for separately scheduled runoffs for winners to get majority support, because votes are counted until a candidate has majority support. New York City spent about $13 million in 2013 for a runoff that drew a turnout rate of 6%, which drew calls to switch to ranked choice voting.
Supporters also point out that ranked choice voting eliminates candidates' winning with extremely low percentages in crowded primaries. For example, Rep. Diana Harshbarger, R-Tenn., won her primary in 2020 with 19% of the vote before she easily won the general election. Rep. Shri Thanedar, D-Mich., won an open primary in 2022 with 28% before he likewise enjoyed an easy general election in a safe district.
'New Yorkers adopted ranked choice voting because they wanted a change from primaries where candidates could win with just 20% of the vote. Now, thanks to RCV, voters have more choice and more voice in who represents them,' Susan Lerner, the executive director of Common Cause New York, said in a statement.
What are the problems with ranked choice voting?
Opponents argue that the system confuses voters and leads to ballots' being thrown out.
Critics also say ranked choice voting lengthens the voting process because voters have to take the time to research all of the candidates. In New York City's case, that includes 11 mayoral candidates on the Democratic side.
New York's 2021 mayor's race was also marred by initial controversy after 135,000 test ballots were accidentally included in one version of the announced election returns as the city used ranked choice voting for the first time.
'Ranked choice voting is like putting your ballot in a paper shredder and hoping democracy miraculously reassembles itself inside the black box of tabulation,' said Madeline Malisa, a senior fellow at the conservative Foundation for Government Accountability.
'The reality is ranked choice voting has been a disaster of delayed results, errors, confusion and voter disenfranchisement everywhere it's been tried. All of those problems erode confidence,' Malisa added.
Some groups have also argued that ranked choice voting disenfranchises minority voters, with several analyses noting that wealthier and whiter neighborhoods had fewer mismarked ballots and more use of ranking.
Though ranked choice voting has spread to a number of jurisdictions in recent years, there have also been efforts to roll it back. In Alaska, voters narrowly passed (by about 1 percentage point) a ballot measure enacting a ranked choice voting system in 2020. Four years later, an effort to repeal the system failed by an even narrower margin, 0.2 points.

Inside NYC's voting system to rank candidates
With so many options, New Yorkers will choose their next mayor like they pick ice cream in the summer. The city's ranked choice system allows voters to choose their top five candidates for mayor, plus top picks in other city races. Even if your top choice doesn't make it, you can still get flavors, or candidates, you prefer. Ranked choice "allows for people to vote in a way that expresses how they feel," said Susan Kang, an associate professor of political science at John Jay College of Criminal Justice. The system aims to give voters more choices in a crowded field of nearly a dozen Democratic and a handful of Republican mayoral hopefuls in closed primaries for both parties. It also hopes to bring up candidates from underrepresented backgrounds, often without access to vast campaign war chests. The system, first approved by voters in 2019, has been used in elections around the country - from Alaska to Maine, and from San Francisco to tiny Woodland Hills, Utah (population 1,571). Other places, including Washington, D.C., more recently adopted it. Australians use the system. Winning New York City's Democratic primary is almost always a ticket to City Hall in a city that's about two-thirds registered Democrats. Primary lessons: Trump rules, Dems are revved. NYC's melee is next. How Cuomo v. Mamdani shows ranked choice voting Andrew Cuomo, New York's longtime governor who resigned in 2021 after multiple women accused him of sexual harassment, had led comfortably in polls. Many voters see Cuomo, 67, as an experienced moderate executive who can fight President Donald Trump. But with ranked choice, state Assemblymember Zohran Mamdani, the 33-year-old democratic socialist calling to freeze rents, has inched ever closer to Cuomo. That's because under ranked choice, a candidate has to get over 50% of votes. While polls have Cuomo ahead, he's unlikely to win most first-round votes. At each round, candidates with the fewest votes get eliminated. Voters who ranked less supported candidates first will have their subsequent choices allocated to their next ranked candidate. New York first used ranked choice voting in 2021. With many candidates vehemently opposed to Cuomo, their supporters' next-round votes can help Mamdani, who is endorsed by Rep. Alexandria Ocasio-Cortez, a progressive star. The process continues until there are two candidates left. Cuomo is favored to win, though polling has tightened between the former governor and Mamdani. Cross-endorsements, cooperation The city's first time using ranked choice, in 2021, resulted in the narrow, eighth-round victory of Eric Adams, the swaggering, scandal-plagued mayor. (Adams dropped out of the 2025 Democratic primary, opting to seek re-election as an independent.) Back in 2021, Adams' last standing opponent, Kathryn Garcia, received a late endorsement from Andrew Yang, another candidate. Yang supported ranked choice during a failed 2020 presidential run. "The ranked choice voting system enables you to take advantage of being someone's second- or third-place vote," Yang, now a third-party advocate, told USA TODA. "A smart candidate will try and capitalize on that." In 2025, there are more cross-endorsements between Mamdani and other candidates to Cuomo's left, such as city Comptroller Brad Lander and former lawmaker Michael Blake. Ranked choice challenges Under this relatively new system, voters need to know how to correctly rank their choices. In a 2023 study, Lindsey Cormack, an associate professor of quantitative social science at Stevens Institute of Technology, found higher levels of voided ballots in lower income areas and communities with lower educational attainment. There were also issues among people who speak a language other than English. "Anytime you change a system, you make it nominally harder, or at least the capacity for errors goes up, because there's just more boxes to tick," she said. Complicating matters, the primaries use ranked choice, but the general election does not. Nor do state or presidential elections. Only growing beyond June 24 primary election Politicians and experts agree that, with time, voters can get used to their new system. For now, ranked choice appears to continue expanding across cities and states. In November, Washington, D.C., approved ranked choice voting. Christina Henderson, one of the district's at-large representatives and a Brooklyn native, has supported ranked choice to help people dissatisfied with polarized politics. "If provided the right information, they can make the right choice for themselves," Henderson, an independent, said. "Now, the key is providing the right information." New York City's primary is June 24. Early voting is underway. Eduardo Cuevas is based in New York City. Reach him by email at emcuevas1@ or on Signal at emcuevas.01.

Democrats could do a lot better with the power they hold
THE VIDEO of Brad Lander getting slammed against a wall and arrested by federal immigration agents shocked New Yorkers, who are not easily shocked. On June 17th the mild-mannered city comptroller had been attempting to escort a migrant through a federal building in Manhattan as agents tried to detain the man. 'It's bullshit,' said Kathy Hochul, the Democratic governor of New York, of Mr Lander's arrest. It came a week before a crowded Democratic primary for New York City mayor, in which the city comptroller is a candidate. The arrest may well help his campaign, but it marked yet another skirmish over immigration with Donald Trump's administration. It is just the latest escalation in a confrontation with cities and states that did not vote for the president, on a topic where the public supports him most.
