Rep. Jerry Nadler’s (D-NY) surprise decision on Monday to retire at the end of his current term has set off what is expected to be a crowded primary to succeed the long-serving Jewish Democrat — with a growing number of candidates weighing bids for the coveted Manhattan House seat he has held for more than three decades.
The looming open-seat primary has also raised questions about whether candidates will embrace Nadler’s increasingly skeptical views on Israel, and how the issue will shape the race. The 78-year-old lawmaker, who represents one of the largest Jewish constituencies in the nation, has long identified as a pro-Israel progressive, even as he has vocally criticized Israel’s conduct during its ongoing war in Gaza and drew scrutiny from some Jewish community leaders over his early endorsement of Zohran Mamdani, the far-left Democratic nominee for mayor of New York City.
In an interview first announcing his retirement on Monday, Nadler, the dean of New York’s congressional delegation, told The New York Times that he believed Israel was committing mass murder and war crimes in Gaza “without question,” and said he would back efforts to withhold offensive weapons transfers to Israel during the rest of his term — in a sharp break from his previous stance on continued military aid to the Jewish state.
It remains to be seen how Nadler’s approach will influence the race. The list of potential candidates includes Micah Lasher, a Jewish assemblyman who is expected to claim Nadler’s blessing, according to people familiar with the situation. Lasher, a former aide to Nadler, has built strong ties to the pro-Israel community, but he faced backlash from local rabbis over his similarly quick choice to support Mamdani, in spite of the nominee’s hostile views on Israel.
One Jewish leader said it was premature to draw conclusions about Lasher’s positions on Israel, while voicing confidence that he “makes up his own mind” on tough issues, regardless of where his allies may stand.
“Lasher is center-left but has always been relatively moderate on Israel,” a pro-Israel strategist added in assessing the assemblyman’s stances on the Middle East.
Still, “the Zohran thing threw a lot of people off,” another Jewish leader said of Lasher, 43. “I do worry with Micah that, because of the political pressures, he could end up turning himself into a Jerry.”
Lasher did not respond to a request for comment from Jewish Insider on Tuesday.
Despite speculation about his approach, Jewish activists and some Democratic strategists broadly suggested that the pro-Israel community would, by varying degrees, likely be comfortable with Lasher, in addition to other lawmakers from state and local office who are said to be mulling campaigns of their own in Nadler’s district, which covers Manhattan’s Upper West and East Sides.
Among them are two City Council members, Erik Bottcher and Julie Menin, who are also eyeing bids for state Senate and Council speaker, respectively. Menin, a Jewish Democrat, was among some local elected officials who chose not to attend a meeting with Mamdani this summer that had been organized by Nadler, a person familiar with the matter told JI. Keith Powers, a city councilman who recently lost a bid for Manhattan borough president and is looking at another open state Senate race, is also weighing a bid, sources said, as is Alex Bores, an assemblyman on the East Side.
“I commend Congressman Nadler for his years of public service,” Bores said in a statement shared with JI on Tuesday, indicating he is exploring a bid for the open House seat. “Rep. Nadler has always led with his convictions and cared deeply about his constituents; that is the exact kind of representation that the people of the 12th Congressional District deserve.”
Pro-Israel strategists indicated that they had more urgent concerns about another possible candidate, Lina Khan, the former commissioner of the Federal Trade Commission and a progressive icon who now lives in Harlem and has been “shopping around for a district for months,” according to a source familiar with the situation.
Khan, whose name has been floated as a potential candidate, could be a prolific fundraiser in a campaign, sources speculated. While she does not appear to have publicly addressed key Middle East questions, the anti-monopoly advocate has praised Mamdani’s campaign, raising early concerns that he would have a close and powerful ally in Congress if both are elected. Khan did not respond to a request for comment about her plans.
In addition to Khan, another prominent figure whose name has been privately mentioned in the days after Nadler’s unexpected announcement is Chelsea Clinton, according to people familiar with the conversations. Clinton has not confirmed her interest in the race to succeed Nadler but is actively considering a campaign after debating a run for an open City Council seat last cycle, said one person informed of her thinking. Her mother, former Secretary of State Hillary Clinton, voiced appreciation for Nadler in a social media post on Tuesday, after he officially announced his departure from the House.
Chelsea Clinton, 45, has been outspoken against antisemitism and would bring considerable name recognition to the race, though pro-Israel activists said they were largely unfamiliar with her views on Israel’s war in Gaza.
The primary is likely to draw outside spending from pro-Israel groups including AIPAC and Democratic Majority for Israel, both of which have engaged in a number of House races where divisions over Middle East policy have fueled mounting tensions amid the war in Gaza.
Brian Romick, chairman of DMFI’s political arm, DMFI PAC, said the group “will be watching closely as the field takes shape and look forward to meeting with the candidates.”
A spokesperson for AIPAC declined to comment on Tuesday.
Two potential candidates who would likely align most closely with AIPAC and are currently weighing bids include Natalie Barth, a philanthropist who has previously served as the president of Park Avenue Synagogue, and Elisha Wiesel, son of the Holocaust survivor and Nobel Peace Prize-winner Elie Wiesel, people familiar with their plans told JI.
Wiesel, who has been critical of Mamdani’s approach to Israel and antisemitism, had endorsed former Rep. Carolyn Maloney (D-NY) when she ran against Nadler in a bitterly contested primary three years ago.
Whitney Tilson, a former hedge fund executive who ran a failed campaign for New York City mayor as a moderate pro-Israel Democrat, is also considering a bid to replace Nadler, writing in a social media post on Tuesday that residents of the district, which had narrowly favored Mamdani in the primary, “have a special responsibility to lead the” fight against President Donald Trump, “defend the rule of law” and “support our allies, especially Israel and Ukraine.”
Shabbos Kestenbaum, a Jewish campus activist who has celebrated Trump’s crackdown on antisemitism, also confirmed to JI on Tuesday that he is weighing a campaign, saying he has been “encouraged to run by a group of New Yorkers from a broad ideological spectrum.”
“I am actively considering it,” he said. “If I can make a positive difference to my city and community, I would be foolish not to. There is a strong desire amongst New York Democrats for a return to normalcy. The party has steered too far to the left and I will help in any way I can, including running for office.”
Other prospective primary candidates include Michael Cohen, the eastern director of the Simon Wiesenthal Center, according to a person familiar with the matter.
Some observers have suggested that Rep. Dan Goldman (D-NY), a moderate Jewish Democrat whose deeply progressive district includes Lower Manhattan and parts of Brooklyn, could potentially jump over to Nadler’s race — where he could face a more friendly electorate and forestall challengers to his left.
But a spokesperson for Goldman, Simone Kanter, dismissed such speculation. “No truth at all, no idea where that’s coming from,” he told JI on Tuesday.
As the field takes shape, Nadler is already facing a younger challenger, Liam Elkind, who in his launch video in July called on the veteran congressman to retire to make room for a new generation of party leadership.
But Elkind, a 26-year-old nonprofit leader who is running on a broadly pro-Israel platform, is likely to face an uphill battle with the primary now expected to draw more well-known rivals with establishment credentials.
