New York City is experiencing its most contentious Congressional primary season in a generation, with major implications for the Democratic Party and the U.S. House. Several high-profile races are drawing significant attention and highlighting internal party divisions. A "Kennedy heir" is among those competing for seats, and various races are seeing substantial financial backing from the tech industry.

Notable contests include incumbent Dan Goldman fending off challenges from figures like former comptroller Brad Lander, whose campaign has centered on Goldman's "corporate Democrat" label and his stance on Israel, specifically his declining to describe Israel's actions in Gaza as "genocide." Lander, in turn, has been called a "career politician" by Goldman. In other districts, young activists are targeting established Democratic figures, and a former prosecutor who participated in President Trump's impeachment is fighting to retain his seat against a longtime local official.

The retirement of veteran Democrats like Jerry Nadler and Nydia Velázquez has created open seats that have attracted a wide range of candidates. The race to succeed Nadler in the 12th Congressional District, covering parts of Manhattan, has become a proxy battle for the artificial intelligence industry, with millions of dollars in spending. One candidate, Alex Bores, co-sponsored an AI-safety bill, leading to a pro-AI super-PAC spending over $7 million against him, while other PACs supported by Anthropic and crypto billionaire Chris Larsen back his campaign. Meanwhile, New York City Mayor Zohran Mamdani is flexing his political influence by endorsing a slate of progressive and democratic socialist candidates, challenging more established figures and testing the viability of socialist platforms.
