As New York voters head to the polls for the June 23 Democratic primary, Mayor Zohran Mamdani is emerging as a major figure in several closely watched congressional contests despite not appearing on the ballot himself. According to a report by ABC7 New York, Mamdani’s endorsements could play a significant role in determining whether progressive challengers can defeat established Democratic incumbents across New York City.
What Happened
Early voting is already underway across New York City, with turnout levels drawing concern from candidates who say voter participation remains low.
Several congressional races have become proxy battles over the future direction of the Democratic Party in New York. Mayor Mamdani has endorsed a slate of progressive candidates, including Claire Valdez in New York’s 7th Congressional District, Brad Lander in the 10th District, and Darializa Avila Chevalier in the 13th District.
These endorsements place Mamdani at odds with some longtime Democratic leaders and incumbents who represent the party’s more traditional establishment wing.
Key Congressional Races to Watch
New York’s 7th Congressional District
The race to replace retiring Representative Nydia Velázquez has attracted significant attention. Candidates include:
- Claire Valdez, a progressive Assembly member backed by Mayor Mamdani
- Antonio Reynoso, Brooklyn Borough President
- Julie Won, New York City Council Member
Valdez has campaigned on labor and economic justice issues, while Reynoso has acknowledged policy differences with Mamdani despite maintaining a generally progressive platform.
New York’s 10th Congressional District
Mayor Mamdani endorsed Brad Lander in a challenge against incumbent Representative Dan Goldman.
Goldman has emphasized his focus on governing and representing constituents rather than political disputes surrounding endorsements.
New York’s 13th Congressional District
Mamdani’s endorsement of Darializa Avila Chevalier against Representative Adriano Espaillat has become one of the most closely watched contests of the cycle.
The race highlights ongoing debates within the Democratic Party over ideology, generational change, and the growing influence of democratic socialist candidates.
Why These Primaries Matter
Political observers view these contests as an important measure of Mayor Mamdani’s influence beyond City Hall.
If multiple endorsed candidates win, it could strengthen progressive organizing efforts and expand the influence of candidates aligned with Mamdani’s policy agenda in Washington. Conversely, victories by incumbents would suggest that traditional Democratic coalitions remain resilient despite shifting political dynamics.
The outcomes may also affect future coalition-building between New York City officials and members of Congress.
What This Means for NYC Candidates
For individuals interested in running for office in New York City, these races provide several important lessons.
Endorsements Can Shape Competitive Elections
High-profile endorsements can help candidates gain visibility, raise funds, and attract volunteers. However, endorsements alone rarely guarantee victory. Candidates must still build strong voter outreach operations and local support networks.
Turnout Often Determines Primary Outcomes
Several candidates have expressed concern about low voter participation during early voting. In many NYC primaries, turnout can be relatively small, meaning campaigns that successfully identify and mobilize supporters often gain a decisive advantage.
Messaging Matters
The current primary season demonstrates how candidates use different messages to appeal to voters. Progressive candidates are focusing on affordability, labor rights, and economic inequality, while incumbents emphasize experience, governance, and constituent services.
Campaign Finance Remains a Key Issue
Debates over super PAC funding and outside spending have become part of the conversation in several races. First-time candidates should understand how campaign finance rules, disclosure requirements, and New York City’s public matching funds system can influence campaign strategy.
For aspiring candidates, understanding ballot access requirements, campaign finance regulations, and district-level voter targeting remains essential to building a competitive campaign.

What Happens Next
Early voting continues through the weekend, with Primary Day scheduled for June 23.
The results will reveal whether Mayor Mamdani’s endorsements can translate into electoral victories and whether progressive challengers can successfully unseat established Democratic figures. The outcome could influence not only congressional representation but also the future direction of NYC politics heading into future election cycles.
Why It Matters
The 2026 primary elections are becoming an early test of political influence, coalition-building, and voter mobilization in New York City.
