Why it Matters
The Democratic primary for New York's 10th congressional district became a study in contrasts on money, endorsements, and political muscle as three candidates competed for the right to represent lower Manhattan and parts of Brooklyn. On one side: the incumbent, Rep. Dan Goldman, armed with a personal fortune and institutional backing. On the other, progressive challenger Brad Lander who built his campaign on small-dollar donations and grassroots energy. Between them is community organizer Nickie Kane with minimal resources.
Goldman's financial dominance is striking. The incumbent raised approximately $2.3 million in the first quarter of 2026 and had approximately $1.5 million in cash on hand after the first quarter of 2026, before accounting for his pledge to inject his own money into the campaign. He raised more than three times what Brad Lander raised in the second quarter 2026, according to campaign filings.
The wealth gap reflects Goldman's personal circumstances. An heir to the Levi Strauss fortune, Goldman carries an estimated net worth of up to $253 million. In his 2022 campaign, he spent nearly $5 million of his own money to win a crowded primary with just 26% of the vote—a 1,306-vote margin over state assemblywoman Yuh-Line Niou.
But Goldman's donor base reveals deeper political alignments. He got more than $377,000 in direct and earmarked AIPAC donations for the 2026 cycle, according to campaign finance disclosures. The pro-Israel contributions have become a flashpoint. Goldman accepted money from an apparent AIPAC front group while publicly disavowing AIPAC donations, a contradiction that has drawn scrutiny from opponents.
AIPAC supporters donated to Goldman's campaign and through a joint fundraising committee, creating a steady stream of pro-Israel money flowing into his coffers. His donor base skews toward large individual donors and includes notable support from AIPAC-aligned contributors.
Lander's fundraising told a different story. The former NYC Comptroller from 2022 to 2025 and longtime progressive organizer raised approximately $700,000 to $750,000 in the first quarter of 2026 with about $650,000 in cash on hand after the first three months. Lander's donor base is fundamentally different: he received donations from 7,000 or more individual donors in the first quarter of the year, with 90 percent of them coming in at less than $100.
Lander's campaign got off the ground last December and had raised $1.4 million total with 11,000 donors through the end of the year. His fundraising is characterized by small-dollar, grassroots contributions rather than large institutional donors. Critically, he has no associations with PAC money frpm major pro-israel groups. That matters as Israel has become become the primary dividing line.
Goldman's campaign ran a sponsored Google ad titled 'Can you trust Brad Lander – Ties to Palantir and ICE', attacking Lander's record as comptroller. While serving in that role, Lander increased NYC pension fund investments in Palantir, a data analytics firm whose technology has been used in immigration enforcement.
Lander struck back by weaponizing Goldman's AIPAC ties. Lander has called for restricting U.S. military aid to Israel.
NY Governor Kathy Hochul backs Goldman as does labor union District Council 37 Lander, meanwhile, earned endorsements from Senator Elizabeth Warren, Representative Alexandria Ocasio-Cortez, and NYC Mayor Zohran Mamdani.
Kane, the third candidate, never mounted a serious challenge. A Brooklyn-based community organizer with no prior elected office experience, Kane ran a self-described 'people-powered campaign' with minimal fundraising and no major endorsements. Her platform centered on housing affordability, tenant protections, and reducing the cost of living, but she was left largely on the sidelines.
Goldman's Record
Goldman's background shaped his political identity. A Democrat born in Washington, D.C. on February 26, 1976, he earned his J.D. from Stanford University in 2005 and served as an assistant United States attorney for the Southern District of New York from 2007 to 2017. After leaving government, he became a regular cable-TV legal news analyst and critic of Trump's ethics.
His entry into electoral politics was unconventional. Adam Schiff hired Goldman in 2019 after meeting him in an MSNBC green room. Goldman directed the House Intelligence Committee's investigative work and was tapped to ask the first questions of each witness during televised impeachment hearings against President Trump.
In Congress, Goldman has focused narrowly on his district's concerns. He has worked to update the formula for funding healthcare for first responders and survivors of the September 11 attack. His legislative output, however, remains minimal: he has introduced 33 bills, cosponsored 60q1 and has yet to have any enacted into law. His voting record shows strong partisan alignment: he cosponsored 520 Democratic bills compared to 76 Republican bills. He cast 1,495 votes while missing 18 votes.
The Bottom Line
Goldman had won his seat convincingly in 2024, reelected with 82% of the vote. But the primary challenge from Lander, a recognizable figure with deep roots in the district poses a genuine threat. Lander served on the NYC City Council for over a decade and represents the tony Park Slope and surrounding neighborhoods. The outcome will signal whether New York's Democratic primary voters valued establishment backing and personal wealth or grassroots energy and ideological consistency on issues like Israel-Palestine policy.

For Kane, the primary was largely a platform to raise her profile in a district where housing and cost-of-living issues dominated voter concerns. But with Goldman's resources and Lander's momentum, she faces long odds.
