In a Mamdani-era primary, J Street endorses pro-Israel incumbent — and, in a first, ‘approves’ his challenger

Rep. Dan Goldman, a two-term Democrat facing a tough primary in New York’s 10th District, has been endorsed again by J Street, but in an unusual move,  the pro-Israel advocacy group will also “approve” Goldman’s opponent, former City Comptroller Brad Lander, who has made Goldman’s stance on Israel and ties to AIPAC central to his campaign.

J Street said it is “proud” to support Goldman for reelection for his “pro-Israel, pro-peace, and pro-democracy leadership” in Congress. “Goldman has worked toward a better future for the Middle East as Congressman, co-leading letters opposing demolition of Palestinian homes and calling for sanctions on some of the most violent extremist settlers in the West Bank,” Jeremy Ben-Ami, J Street’s president, said in a statement shared with the Forward.

Goldman called J Street a “vital organization that squarely aligns with my support for Israel as a Jewish and democratic state” and one that “represents many of my Jewish and progressive values, like justice, equality, freedom, and the pursuit of peace.”

J Street first endorsed Goldman, an heir to the Levi Strauss fortune who was elected in a competitive primary in 2022, in the 2024 election; as an incumbent, he was automatically included on J Street’s early endorsement list of 117 House members. The group is now reaffirming its backing of Goldman as he faces an uphill battle in a district that voted for Zohran Mamdani, a democratic socialist and strident critic of Israel, in the Democratic primary for Mayor — after Lander cross-endorsed him, and overwhelmingly backed him in the general election against former Gov. Andrew Cuomo.

Mamdani is backing Lander’s bid, while Goldman has the support of Gov. Kathy Hochul, House Democratic Leader Hakeem Jeffries, former House Speaker Nancy Pelosi, and Manhattan Borough President Brad Hoylman-Sigal.

Palestinian rights and the Gaza war have increasingly become a litmus test for progressive candidates seeking to define themselves against establishment Democrats. The stakes are heightened by the makeup of the district’s electorate and the fact that both candidates are Jewish, making Israel a key issue in the race. Jewish voters are estimated to comprise more than 20% of the Democratic primary electorate in the 10th Congressional District, which encompasses the Brooklyn neighborhoods of Borough Park and Park Slope, along with a swath of lower Manhattan.

At his campaign launch in Chinatown last week, Goldman said that his Israel positions reflect where most voters in the district are: supportive of Israel’s security while finding a pathway for a two-state solution, sharply critical of Prime Minister Benjamin Netanyahu’s right-wing government, and opposed to settlement expansion and settler violence. Last November, Goldman co-led a letter to President Donald Trump urging for the re-imposition of the Biden era sanctions on West Bank settlers.

Goldman was also an early supporter of humanitarian pauses in the war against Hamas to allow the flow of humanitarian aid. Recently, he told The New York Times, he would “likely vote differently” on a resolution to censure Rep. Rashida Tlaib, the only Palestinian American House member, for her comments on Israel. More than 1,000 constituents protested outside his district office after his vote in favor of the Republican-led measure.

Goldman diverged from J Street on key Gaza-related efforts, including his opposition to Democratic-led measures to block or condition U.S. arms transfers to Israel or his refusal to sign onto a letter opposing Trump’s initial vision of the U.S. taking control of Gaza and turning it into the “Riviera of the Middle East.”

Risa Levine, an advocate and an active member of J Street, said it’s a “no brainer” to reaffirm support for Goldman given that on Israel and issues related to the Jewish community, he is “100% where the J Street membership is” and “very amenable to everything that J Street says” even when there are disagreements about certain policies.

Levine, who as a constituent has attended private meetings with Goldman, said that describing Goldman as being owned or directed by AIPAC is “kind of silly,” given his personal wealth, estimated at up to $253 million. Goldman loaned his campaign $4 million in 2022;  AIPAC’s super PAC later said it contributed $350,000 to a local super PAC opposing his chief rival at the time, Yuh-Line Niou, who supports the boycott Israel movement.

Lander’s J Street seal of approval

The endorsement of Goldman underscores the bind J Street now faces, placing itself squarely in the middle of a complex and contentious primary.

Lander is widely regarded inside the organization as a family figure. He is a regular speaker at its annual conferences, and activists and donors view Lander as a natural standard-bearer for the group in the post–Gaza war and Mamdani era.

J Street is expected to break with past practice and list Lander as one of seven  “primary-approved” House candidates, but the only challenger to an incumbent it supports. That designation would allow donors to contribute to his campaign through the J Street PAC portal but stops short of organizing events or offering active campaign support.

In an interview on Monday, Lander called the group’s decision to approve his candidacy “significant.”

Lander also insisted that he is “better aligned” with the views of this district on the Israeli-Palestinian conflict, an issue, he said, which will be important for voters in the race.

Though Lander opposes the Boycott, Divestment, Sanctions movement, he supported Ben & Jerry’s decision to end sales in the occupied West Bank in 2021. Since Oct. 7, Lander has regularly attended a weekly rally against the Israeli government’s handling of the war in Gaza, has backed calls for a permanent ceasefire and has met with families of Israeli hostages.

In September, he expressed regret for not doing enough “to speak out against Israel’s war crimes, against ethnic cleansing, against forced starvation of Palestinians.” More recently, he described the war as “genocide,” inspired by the writings of Raphael Lemkin, who coined the term, which his daughter had given him. J Street’s head said he was “persuaded” by arguments that Israel is committing genocide in Gaza.

As comptroller, Lander also ended New York City’s half-century practice of investing millions in Israeli government debt securities in 2023.

Ruth Messinger, the trailblazing Jewish political leader who in 1997 became the first and only woman to win the Democratic nomination for New York City mayor, praised J Street for having “flexibility” in maintaining their relationship with Goldman, but also designating Lander as an approved candidate.

Lander, she said, “speaks really directly to the perspective of the people in this district on these issues, and J Street is correct in recognizing that.” Messinger, who endorsed Mamdani after the primary and said his views on Israel were not central to the job he was seeking, added that Lander would be a strong fit to succeed retiring Rep. Jerry Nadler — the longtime dean of the Congressional Jewish Caucus — and to “play this critical role” in shaping the thinking of both Jewish and non-Jewish members of Congress.

Levine said the endorsement of Goldman “speaks for itself” and that she would prefer J Street not feature Lander’s name as a primary challenger, so as not to create divisiveness within the party. She added that the endorsement could help Goldman appeal to voters who may have supported Lander’s mayoral candidacy.J Street’s Ben-Ami told the Forward, “At the end of the day, it is a win for the district and the nation to have two J Street-aligned voices in this race.”
