Progressive Wave Gains Momentum in New York as Mamdani Allies Win Big

Two Democratic primary victories Tuesday night are signaling a shift in New York City politics, strengthening the hand of mayoral candidate Zohran Mamdani and his progressive coalition.

Assemblymember Claire Valdez held her Queens seat against challenger Josh Waldo, while community organizer Darializa Avila Chevalier claimed victory in a competitive race for City Council in the Bronx. Both candidates ran campaigns centered on affordable housing, tenant protections, and workers’ rights—issues that have become hallmarks of the city’s ascendant left wing.

The wins add to a growing list of successes for candidates aligned with Mamdani and the Democratic Socialists of America, which has quietly built a formidable political machine across the five boroughs over the past few years.

“These results show that voters are hungry for change,” said political analyst Maria Chen, who has tracked the DSA’s rise in city politics.

Valdez, a first-term assemblywoman, campaigned heavily on healthcare access and public transportation improvements alongside her focus on housing and labor issues. Avila Chevalier, who has spent years fighting for tenant rights, made immigrant protections and education funding central to her pitch.

The victories come as Mamdani’s mayoral campaign has gained traction among younger voters and those frustrated with the status quo. Political observers say the results reflect serious organizational work by progressive groups that have managed to mobilize grassroots support across multiple neighborhoods.

With November’s general election looming, Tuesday’s primary wins could provide crucial momentum—and a clearer picture of just how much power the progressive wing now wields within the city’s Democratic Party.
