Reps. Laura Gillen (D-NY), Tom Suozzi (D-NY) and George Latimer (D-NY) declined to support State Assemblyman Zohran Mamdani, the presumptive Democratic nominee for mayor of New York City, citing ongoing concerns about his ideological record, as many other prominent politicians in the state fell in line.

“Socialist Zohran Mamdani is too extreme to lead New York City,” Gillen said, highlighting his calls for higher taxes and what she described as unrealistic campaign promises. “Beyond that, Mr. Mamdani has called to defund the police and has demonstrated a deeply disturbing pattern of unacceptable antisemitic comments which stoke hate at a time when antisemitism is skyrocketing. He is the absolute wrong choice for New York.”

“I had serious concerns about Assemblyman Mamdani before yesterday, and that is one of the reasons I endorsed his opponent. Those concerns remain,” Suozzi said. Suozzi, once a close ally of New York Mayor Eric Adams, endorsed former Gov. Andrew Cuomo in the final weeks of the race, explaining “I don’t want the socialists to win.”

Latimer, who also endorsed Cuomo, said he was surprised by Mamdani’s performance, credited him with a “very energetic campaign” and called him “clearly a very charismatic figure.” But he was also clear that he was not endorsing Mamdani and left open the possibility of endorsing a third-party challenger.

“I haven’t thought about it at all yet, check back with me once things shake out. I don’t want to be presumptive if I don’t know what’s going to happen,” Latimer told reporters, referring to potential uncertainties around whether Adams, Cuomo and Republican Curtis Sliwa stay in the race. “I’m not endorsing anybody at this point.”

He said that he was concerned that “running New York City is an extremely complicated situation … it takes a certain mindset not to just advocate for policies — as popular as they are — but to actually accomplish them.” Latimer said Mamdani would likely have to appeal to the state Legislature and would face difficult cash crunches as he seeks to implement his signature, and costly, campaign promises.

“I know how popular it would be for me to say things and promise things. I try to be careful about what I promise because whether I can deliver it or not becomes the first test of whether I’m effective in that office,” he continued.

Asked by Jewish Insider about Mamdani’s record on antisemitism, Latimer highlighted his own opposition to and work on combating hate.

“You shouldn’t have to feel afraid to walk in the streets with yarmulke on. … You should be treated for who you are as a person,” Latimer said. “So to the extent that you know there’s, there’s a sense that there’s an antisemitic moment, then we can’t add code words and make it worse, we have to fight to try to have people be treated equally all across the board, including those who are Jewish.”

Both Gillen and Suozzi represent Long Island-based swing districts in the outskirts of New York City. Suozzi’s district includes a slice of Queens. Latimer’s district is primarily in Westchester County, but includes a small piece of the Bronx.

Rep. Jerry Nadler (D-NY), meanwhile, endorsed Mamdani on Wednesday, after backing one of his primary challengers, saying Mamdani was committed to fighting antisemitism.

Nadler, a co-chair of the House Jewish Caucus, said he had “spoken to [Mamdani] today about his commitment to fighting antisemitism, and we’ll work with all New Yorkers to fight against all bigotry and hate.”

“Voters in New York City demanded change and, with Zohran’s triumph, we have a direct repudiation of Donald Trump’s politics of tax cuts and authoritarianism,” Nadler added, describing Mamdani as a future “partner to me in Washington to take on Donald Trump.”

Other prominent New York Democrats including Sens. Chuck Schumer and Kirsten Gillibrand and House Minority Leader Hakeem Jeffries have offered praise for Mamdani in the hours since his victory, declining to address his antisemitic history. They held back explicit endorsements.

Reps. Alexandria Ocasio-Cortez (D-NY) and Nydia Velazquez (D-NY) supported Mamdani in the primary. No other New York Democratic lawmakers responded to requests for comment.

In the region’s northern suburbs, Mamdani’s candidacy is likely to emerge quickly as a hot-button issue in the swing district race in New York’s 17th Congressional District, which is home to a substantial Jewish population.

Rep. Mike Lawler (R-NY), the 17th District incumbent, has repeatedly attacked Democratic leaders across the state over Mamdani’s victory, particularly highlighting his record on antisemitism.

“Democrats need to make very clear to voters where they stand on this,” Lawler told reporters. “You’ve already had Laura Gillen speak out against it, and yet, Hakeem Jeffries, Chuck Schumer and Kathy Hochul put together the most gobbly-gook bull***t statements I’ve ever seen in my life, saying nothing about anything except that they’re going to continue to speak with him, whatever the hell that means.”

Three of the seven Democratic 17th District candidates who responded to questions from Jewish Insider about Mamdani took divergent approaches.

Cait Conley, a former national security official, told JI that she does “not agree with the direction Zohran wants to take NYC. We need to address affordability but not by raising already exorbitant taxes on New Yorkers that will just drive more people out of the state. We need to stand up for the NY Jewish community and stand against anti-semitism in all forms.”

Conley argued that the election results show that voters are looking for alternatives, like herself, to career politicians, adding, “I will never stop standing up to hate. Anti-semitism is on the rise across this country which is both unacceptable and un-American.”

Jessica Reinmann, a nonprofit executive, told JI, “The results of last night’s NYC mayoral race underscore the need for the kind of boots-on-the-ground, community-focused effort that Team Reinmann is building — one focused on kitchen-table issues, meeting people where they are, and addressing their concerns.”

“That said, there should be no tolerance in the Democratic Party for candidates who espouse antisemitic and hateful views,” Reinmann continued. “Team Reinmann is building a coalition that is built on respect for all people, no matter who they pray to, where they come from, who they love, or the color of their skin.”

Peter Chatzky, a tech company founder and deputy mayor of Briarcliff Manor, N.Y., praised Mamdani for “an effective campaign that consistently focused on affordability, fairness, and opportunity in New York City.”

“The Democratic Party needs candidates who are hearing constituent concerns and will take on the Trump administration and fight for the people of their districts,” Chatzky said. “I am excited to bring that message to the voters of the Hudson Valley.”

Pressed on Mamdani’s record on antisemitism, Chatzky added, “To be clear, antisemitism is serious and a real threat to Jewish New Yorkers and needs to be taken with utmost seriousness. It is something I will be on the forefront of for the people of the 17th District every day.”

Neither Gillen nor Suozzi indicated whether they plan to support an alternative candidate like Adams, the incumbent who is running as an independent in the general election.

Suozzi said, when he endorsed Cuomo, that he still likes Adams, but argued he’s too mired in scandal to continue to lead. Adams’ team praised Suozzi’s record even after his endorsement of Cuomo.

Gillen, meanwhile, publicly clashed with Adams at a House Oversight Committee hearing earlier this year, saying she had “no confidence” in his leadership and calling on him to resign. She said previously that he had “failed and betrayed New York City repeatedly” and engaged in “blatant, textbook corruption. She has said that New York Gov. Kathy Hochul should remove him from office.

Given that Mamdani appears headed for a fairly sizable margin of victory in the primary and the city’s largely Democratic electorate, any third-party challenge will be a tough lift.

Cuomo hasn’t confirmed yet whether he will seek to run in the general election as an independent, a prospect that could further complicate efforts for Mamdani opponents to coalesce.
