Left Earthquake Shakes Brooklyn, Queens

Zohran Mamdani’s latest win in New York shows how fast the city’s left wing is gaining power.

Quick Take

Claire Valdez won the Democratic primary for New York’s 7th Congressional District and is projected to be the nominee.^[1]^[2]
Mamdani-backed candidates won all three House primaries he supported, giving the left a clear night of wins.^[1]^[4]^[10]
Valdez ran as a democratic socialist and won strong support from young, college-educated, Hispanic, and higher-income voters.^[1]^[2]
Critics say her campaign raises fair questions about super PAC money, a “red box” on her site, and her response to an immigration arrest.^[4]

Valdez’s Win and What It Means

Claire Valdez won the Democratic primary in New York’s 7th Congressional District, which covers parts of Brooklyn and Queens, and The New York Times said the race was becoming a “left vs. lefter” fight.^[1] Valdez is a democratic socialist and a Mamdani ally, and national outlets said her victory added to a larger sweep for the mayor’s preferred candidates.^[2]^[4] That gives Mamdani a stronger grip on the city’s left flank.

The vote numbers show a clear base, but not a broad coalition. Valdez led among young voters, college-educated areas, Hispanic communities, and higher-income areas.^[1] At the same time, Reynoso ran far better in majority Black and lower-income areas.^[1] That split matters because it shows how today’s Democratic fights are less about party labels and more about which voters each side can still trust.

Money, Messaging, and the Red Flags Around the Campaign

Valdez has said she rejected corporate and fossil fuel political action committee money, relied on 22,000 individual donors averaging $50, and built a volunteer base of more than 3,000.^[4] Her supporters present that as proof of a real grassroots campaign. Critics, however, point to claims that five super political action committees helped fund her race and to a “red box” on her website that they say signals outside spenders where to focus.^[4] Those disputes are now part of her political brand.

The campaign’s policy pitch also leaves room for attack. Valdez has called herself a proud democratic socialist and said she helped secure $100 million for public renewable energy in the New York State budget.^[4] But opponents note that she voted against the revenue portion of that budget while saying it did not raise taxes enough on wealthy New Yorkers and corporations.^[4] That gives her critics an opening to argue that her rhetoric and votes do not always match.

Why the Broader Political Fight Is Getting Sharper

Valdez’s win matters beyond one district because it fits a larger pattern of organized left-wing candidates beating more traditional Democrats in deep-blue areas.^[10] Fox News and The New York Times both framed the result as another sign that Mamdani has become a real kingmaker inside New York Democratic politics.^[1]^[2] For conservatives, that looks like proof that the party keeps moving left. For moderates, it raises new fears about losing control of the center.

The deeper issue is trust. Valdez’s supporters see a movement built on labor, volunteers, and small donors.^[4] Her critics see a polished socialist message wrapped around outside money and selective outrage.^[4] The vote itself does not settle those arguments. It does show that a growing share of New York Democratic voters is willing to reward candidates who talk openly about socialism, immigration resistance, and a bigger role for the state, even when the rest of the party is still debating where that road leads.
