Former New York City Comptroller Brad Lander has soundly defeated U.S. Rep. Dan Goldman (D-NY) in the Democratic Party primary for New York’s 10th Congressional District. Lander, who was backed by New York City Mayor Zohran Mamdani, ran to Goldman’s left and made the Israel-Palestine conflict a central them of his campaign.
Lander was declared the winner by Decision Desk HQ just minutes after polls closed at 9 p.m. Eastern Time. The quick race call reflects recent polling, which positioned Lander well in the lead over the incumbent.

Lander previously served on the New York City Council and represented Brooklyn’s 39th District from 2010 to 2021. During his council tenure, he co-founded the Council’s Progressive Caucus. In 2021, he was elected New York City Comptroller, and served from 2022 until early 2026. In that role, he oversaw the city’s finances, audited government operations, and managed public pension investments.
In the 2025 Democratic primary for Mayor of New York City, Lander ran as one of multiple candidates in a ranked-choice voting contest. He placed third in the initial round of voting behind then-State Assembly Member Zohran Mamdani and former Governor Andrew Cuomo.
Mamdani and Lander cross-endorsed each other during the campaign. After Lander was eliminated, a majority of his voters’ second and subsequent preferences transferred to Mamdani. Mamdani won the nomination in the final round and later won the general election, becoming mayor.
Following Mamdani’s election as mayor, Lander announced his candidacy for the U.S. House in New York’s 10th Congressional District.
Lander positioned his campaign to the left of incumbent Goldman on several policy areas. The Israel-Gaza conflict emerged as a prominent issue in the primary, as Lander described Israel’s military campaign in Gaza as genocide and stated he would oppose additional U.S. military aid to Israel while it continues operations he views as violating international law and Palestinian human rights.
Goldman, who is Jewish, has expressed support for Israel as a Jewish and democratic state, voted for U.S. military aid packages to Israel, and declined to apply the term “genocide” to Israel’s actions in Gaza. He has emphasized support for a ceasefire, humanitarian aid, and a two-state solution while arguing that the legal definition of genocide requires specific evidence.
New York’s 10th Congressional District covers portions of Lower Manhattan and Brooklyn, including neighborhoods such as Park Slope. The district carries a Cook Partisan Voting Index rating of D+32, based on presidential election results.
Lander is essentially a lock to win election in November.
