The role of labor union endorsements in NYC elections is changing as recent primary results challenge long-held assumptions about organized labor’s influence in local politics. According to a report by City & State New York, several progressive candidates won high-profile races despite lacking support from many of New York City’s largest labor unions, prompting political strategists and labor leaders to reassess how unions influence elections—and governance after Election Day.
For candidates considering a run for office in New York City, the shifting relationship between labor organizations and political campaigns offers important lessons about coalition-building, voter outreach, and long-term governing partnerships.
What Happened?
The article examines a series of recent New York City and congressional primary elections in which candidates prevailed despite missing endorsements from many of the city’s traditional labor powerhouses.
Among the races highlighted:
- Mayor Zohran Mamdani won the 2025 Democratic mayoral primary without endorsements from several of New York City’s largest unions.
- Congressional candidates Claire Valdez and Darializa Avila Chevalier won Democratic primaries despite major labor organizations supporting their opponents.
- Congressman-elect Brad Lander secured victory after receiving backing from some unions, including 32BJ SEIU, while many larger organizations endorsed incumbent Rep. Dan Goldman.
These outcomes have fueled debate over whether organized labor’s electoral influence is declining or simply evolving.
Traditional Labor Endorsements No Longer Guarantee Victory
For decades, endorsements from major labor organizations were considered one of the most valuable assets for Democratic candidates in New York.
Large unions traditionally provided:
- Campaign volunteers
- Independent expenditures
- Financial support
- Member outreach
- Political credibility
However, the recent election cycle demonstrated that candidates can assemble successful coalitions through grassroots organizing, digital engagement, and direct voter contact—even without widespread institutional labor support.
Political consultant Eli Valentin told City & State that while labor continues to influence elections and policymaking, broader political shifts are changing the electoral landscape.
Grassroots Organizing Played a Larger Role
One organization highlighted in the report was the United Auto Workers (UAW) Region 9A, which endorsed several eventual winners early in their campaigns.
Rather than relying primarily on financial resources, UAW emphasized member-driven organizing.
According to the report, union members knocked on more than 50,000 doors during the campaign cycle, helping support candidates through direct voter engagement.
Brandon Mancilla, director of UAW Region 9A, argued that labor’s influence depends on active organizing rather than endorsements alone, while Claire Valdez credited member-led organizing as a model other unions could adopt.
Labor’s Role Doesn’t End on Election Day
Although some candidates won without major labor endorsements, the article argues that organized labor remains an influential force after elections conclude.
Successful candidates often continue working with unions on issues including:
- Collective bargaining
- Public workforce policy
- Housing
- Transportation
- Education
- Labor standards
Several newly elected officials participated in UAW picket lines shortly after their victories, illustrating that governing relationships with organized labor often continue regardless of endorsement decisions made during campaigns.
Political observers interviewed by City & State cautioned against interpreting recent election results as evidence that labor has lost its broader policy influence.
Why This Matters for NYC Candidates
For anyone planning to run in NYC elections, the changing role of labor union endorsements offers several strategic lessons.
Candidates should recognize that endorsements remain valuable, but they are only one component of a successful campaign.
Modern campaigns increasingly require:
- Strong grassroots organizing
- Authentic voter engagement
- Clear campaign messaging
- Effective district strategy
- Consistent community presence
- Digital outreach alongside traditional field operations
Candidates who invest in direct relationships with voters may be able to build competitive campaigns even without securing every major institutional endorsement.
At the same time, maintaining constructive relationships with labor organizations remains important because unions continue to influence legislation, public policy, and governing coalitions after elections.

Campaign Strategy Lessons for First-Time Candidates
The recent election cycle demonstrates that campaign success depends on combining multiple forms of voter outreach rather than relying on any single endorsement.
First-time candidates should focus on:
- Building neighborhood relationships early.
- Developing a strong volunteer network.
- Creating clear issue-based messaging.
- Understanding district-specific voter priorities.
- Maintaining relationships with community organizations, including labor groups.
Endorsements can strengthen a campaign, but sustained voter engagement remains one of the most important factors in competitive elections.
Conclusion
Recent primary elections suggest that the political influence of labor unions in New York City is evolving rather than disappearing. While endorsements from major unions continue to matter, successful candidates are increasingly combining grassroots organizing, direct voter engagement, and community-based campaigning to build winning coalitions.
For candidates preparing to run for office in New York City, the lesson is clear: labor relationships remain valuable, but long-term success depends on earning voter trust before the election and maintaining productive partnerships with organized labor after taking office.
Yes. Labor endorsements remain influential, but recent elections show they are no longer the sole predictor of electoral success as grassroots organizing plays a larger role.
Candidates should combine community outreach, volunteer organizing, clear messaging, and relationship-building with labor organizations instead of relying solely on endorsements.
