Brad Lander Wins NY‑10 Democratic Primary, Shifting Congressional Delegation Leftward
Former New York City Comptroller Brad Lander defeated two‑term incumbent Rep. Dan Goldman in the Democratic primary for New York’s 10th Congressional District on June 24, 2026. NBC News projected Lander’s victory after a campaign that highlighted stark differences on foreign‑policy, especially the U.S. role in the Israel‑Gaza conflict.
Lander, a longtime progressive and former city comptroller, was projected to win with a commanding lead, outpacing Goldman by more than 30 points in the final count. The race, long‑anticipated as a test of Mayor Zohran Mamdani’s influence, saw the mayor introduce Lander at a victory rally, describing him as a “good neighbor who will always have our backs.”
Central to Lander’s appeal was his criticism of Israel’s war in Gaza. He repeatedly called Israel’s actions a “genocide” and pledged to co‑sponsor legislation that would impose new restrictions on U.S. military aid to the country. By contrast, Goldman, while Jewish and historically supportive of Israel, positioned himself as a “liberal Zionist,” refusing to label the conflict as genocide and drawing criticism from progressive voters who have become increasingly hostile to unconditional support for Israel.
Endorsements played a pivotal role. Lander secured backing from high‑profile progressives, including Senators Bernie Sanders and Elizabeth Warren, as well as local leaders such as City Councilmember Shahana Hanif and activist groups like Jews for Racial and Economic Justice. In stark contrast, Goldman leaned on establishment support, receiving endorsements from House Democratic Leader Hakeem Jeffries, Governor Kathy Hochul, and the pro‑Israel lobby AIPAC, whose involvement was cited by Lander’s campaign as evidence of Goldman’s alignment with corporate interests.
Lander’s campaign also emphasized his record on immigrant rights. He highlighted two arrests during protests against federal immigration detention, both resulting in acquittals, underscoring his “hands‑on” approach to defending vulnerable communities. These experiences resonated with a district that has seen a surge in progressive activism, especially after Mayor Mamdani’s own mayoral bid rallied left‑leaning voters.
Financially, Goldman outspent Lander more than 7‑to‑1 on television advertising, leveraging his personal wealth and family legacy. Yet, the spending advantage failed to quell the momentum behind Lander’s grassroots message, which centered on ending what he described as “Israel’s war crimes,” expanding affordable housing, and pursuing “Medicare for All.”
The primary’s outcome effectively guarantees Lander a seat in the U.S. House, given the district’s heavy Democratic tilt and the absence of a competitive Republican challenger. Observers note that his victory not only reshapes New York’s representation but also adds to a broader leftward surge within the Democratic Party, as progressive candidates backed by Mamdani secured additional congressional primaries across the city.
In his post‑win address, Lander thanked volunteers, praised Mamdani’s leadership, and pledged to be a “Jewish member of Congress most willing to stand up for Palestinian human rights.” He urged constituents to continue the fight for economic justice, climate action, and immigrant protections, positioning his upcoming term as a continuation of the progressive wave that has transformed New York City politics in recent years.
