Mayor Zohran Mamdani’s Endorsed Candidates Sweep Brooklyn Primaries

In a decisive turn, three candidates backed by New York City Mayor Zohran Mamdani won all contested Democratic primaries in Brooklyn and Queens.

Key Victories

Brad Lander, a progressive challenger, defeated the two‑term incumbent Dan Goldman in the 10th‑District with 65.7% of the vote, illustrating mounting discontent over the Israel‑Gaza conflict. Assemblywoman Claire Valdez edged out incumbent borough president Antonio Reynoso in the 7th District, while Darializa Avila Chevalier, a former Columbia protester, captured the 13th‑District seat.

Political Implications

The outcomes signify a sharp leftward shift in Midtown politics, with all Mamdani‑endorsed candidates promoting reforms such as abolishing ICE and taxing the wealthy. However, establishment Democrats caution that these novel platforms may struggle to resonate with moderate voters in the upcoming national elections.

Congressional Shift

Dan Goldman, an heir to the Levi Strauss denim fortune and former lead on Trump’s impeachment inquiry, conceded his defeat with respectful comments, while President Donald Trump mocked the outcome via social media.

Broader Context

The 12th‑District race also saw former President John F. Kennedy’s grandson Jack Schlossberg defeat Assemblymember Micah Lasher, and conservative lawyer George Conway secured only a small share of votes. The mayor’s endorsement strategy reflects a broader push for a redefined Democratic agenda in New York City.
