Mamdani Delivers 8 Primary Wins, Cementing New York Political Machine
3 articles · Updated · City & State New York · Jun 29
Summary
Eight candidates endorsed by Mayor Zohran Mamdani won on June 23, capping a months-long effort in which he personally campaigned through rallies, fundraisers, videos, canvasses and phone banks.
Since winning the mayoralty in November, Mamdani and his team worked with NYC-DSA to recruit contenders, clear fields and steer key races, including backing Claire Valdez for Congress and Brad Lander against Rep. Dan Goldman.
That push also required risky breaks with allies: Mamdani backed Valdez over Nydia Velázquez’s preferred successor, blocked support for Lt. Gov. Antonio Delgado’s challenge to Gov. Kathy Hochul, and later endorsed Darializa Avila Chevalier over Rep. Adriano Espaillat.
The victories leave Mamdani looking like the city’s strongest mayoral kingmaker in generations, though his power still rests on a strategic alliance with NYC-DSA rather than a fully independent machine.
Having built a powerful political machine, can Mamdani govern effectively without alienating the allies he needs for his agenda?
After freezing rents, how will Mamdani's administration prevent a citywide decline in housing quality and supply?

Overview
In June 2026, Mayor Zohran Mamdani led a dramatic shift in New York City politics by deeply involving himself in the Democratic congressional primaries. His bold strategy, though it alienated some key allies, paid off as Mamdani-backed progressive candidates ousted two incumbent members of Congress and won a third open seat. This successful sweep challenged the established Democratic order and signaled a strong move toward a more left-leaning direction. Mamdani’s actions fundamentally reshaped the city’s political landscape, marking a new era of progressive influence in New York City.
