Progressive Showdown: Brad Lander Challenges Dan Goldman in NY-10 Democratic Primary

New York City Comptroller Brad Lander will challenge U.S. Representative Dan Goldman. The high-profile Democratic primary battle is set for 2026. The race will unfold in New York’s 10th Congressional District. This district covers parts of Lower Manhattan and northwest Brooklyn.

Lander’s campaign launch signals a major clash within the party. He is positioning himself as a progressive alternative to the incumbent. The contest will test the strength of the Democratic Party‘s left wing in a deep-blue seat.

Key Endorsements and Ideological Divide

Lander announced his candidacy on Wednesday, December 10. He enters the race with significant progressive backing. Vermont Senator Bernie Sanders has endorsed him. So has New York City Mayor-elect Zohran Mamdani.

In his announcement, Lander framed the race as a fight against wealth. He took a clear shot at Goldman’s personal fortune. Goldman is an heir to the Levi Strauss denim empire. Lander criticized what he called an overly cautious political approach.

He vowed to provide “courageous leadership.” He specifically mentioned facing Donald Trump‘s policies. According to the Associated Press, Lander emphasized his alliance with Mamdani. This contrasts with Goldman’s refusal to endorse Mamdani in the mayoral race.

Local Alliances and National Implications

The alliance between Lander and Mamdani is a central theme. They formed a ranked-choice partnership during the NYC mayoral primary. That move helped propel Mamdani to a surprise victory. It also solidified Lander’s standing with progressive voters.

Lander stated the city’s mayor needs an ally in Washington. He suggested Goldman has been an adversary locally. Mamdani returned the favor with strong praise. He called Lander a leader with “unwavering principles and deep knowledge.”

Both candidates have been visible on immigration issues. They frequently appear at federal deportation proceedings in Manhattan. Lander’s term as comptroller ends on December 31. He chose not to seek re-election for that city post.

This primary is being watched nationally. It represents a growing effort by progressives to challenge moderate Democrats. Mamdani’s endorsement marks his big step onto the national stage. The 2026 race in NY-10 is now a premier battleground.

This primary contest will define the direction of New York City’s Democratic politics. The NY-10 primary has become a focal point for the party’s internal debate. The outcome could influence similar races across the country.
