NEW YORK — Their chances of becoming the next mayor of New York City may have dimmed. Their mission now? Stopping former Gov. Andrew Cuomo from getting to City Hall.

In the final day of campaigning before the city’s Democratic primary, candidates who are seen as long shots to win the nomination were urging voters to leave Cuomo off their ballots in the city’s ranked choice election in a last-ditch effort to block the former governor’s comeback from a sexual harassment scandal.

“Let’s make sure Andrew Cuomo gets nowhere near City Hall,” candidate and city Comptroller Brad Lander said Monday on WNYC radio, which interviewed the major candidates ahead of the election.

State Sen. Zellnor Myrie, another candidate, similarly asked voters to not vote for Cuomo, telling the station, “We need fresh leadership, we need to turn the page and we need bold solutions at this moment.”

The pitches came as Cuomo, who has been considered the frontrunner for months, has also been trying to fend off a charge from Zohran Mamdani.

Mamdani, a 33-year-old state assemblyman, would be the city’s first Muslim and first Indian-American mayor if elected. A democratic socialist who got elected to the Legislature in 2020, Mamdani started the campaign as a relative unknown but has won support with a energetic campaign centered on improving the cost of living.

The assault on Cuomo from fellow members of the Democratic field comes as he has continued to rack up establishment endorsements. Former President Bill Clinton endorsed Cuomo on Sunday, saying voters should not “underestimate the complexity” for the challenges faced by a mayor. The New York Times didn’t issue an endorsement this year, but wrote an editorial praising Lander and saying Cuomo would be a better choice than Mamdani, who it said was unworthy of being on people’s ballots.

Cuomo and Mamdani have ratcheted up attacks on each other in the campaign’s final days.

In a way, Mamdani and Cuomo represent the Democratic Party’s ideological divides, with Cuomo as an older moderate and Mamdani a younger progressive.

Cuomo, who won three terms as governor, resigned in 2021 after a report from the state attorney general concluded that he sexually harassed 11 women. He has denied wrongdoing.

New York City is using ranked choice voting in its Democratic mayoral primary election Tuesday, a system that allows voters to rank up to five candidates in order of preference. If one candidate is the first choice of a majority of voters, that person wins the race outright. If nobody hits that threshold, the votes are then tabulated in multiple rounds. After each round, the candidate in last place is eliminated. Votes cast for that person are then redistributed to the candidates ranked next on the voter’s ballot.

That continues until one candidate gets a majority.

Cuomo’s opponents have urged voters not to rank him at all and therefore deprive him of support in later rounds of counting.
