New York City Mayor Zohran Mamdani recorded a significant political victory after all three Democratic congressional candidates he endorsed won their primary elections, according to projections from major US media outlets.
The results are being viewed as an important test of Mamdani’s growing influence within the Democratic Party and could signal a broader shift in the party’s direction ahead of the November 2026 midterm elections.
Darializa Avila Defeats Incumbent Adriano Espaillat
One of the biggest surprises came in New York’s 13th Congressional District, where Democratic candidate Darializa Avila defeated incumbent Congressman Adriano Espaillat.
Espaillat, a veteran lawmaker and chairman of the Congressional Hispanic Caucus, had been considered a formidable incumbent. However, election projections showed Avila taking the lead as votes were counted.
With approximately 88% of ballots reported, projections indicated that Avila held around 49% of the vote, while Espaillat trailed with nearly 46%.
The result represents one of the most notable incumbent defeats in New York’s Democratic primaries.
Claire Valdez Wins in the 7th District
In New York’s 7th Congressional District, Claire Valdez secured a convincing victory over Antonio Reynoso.
The contest was closely watched because it was effectively a race to succeed outgoing Representative Nydia Velázquez.
According to projections, Valdez captured more than 56% of the vote, while Reynoso received nearly 36%, giving her a comfortable margin of victory.
The outcome further strengthened the impression that candidates aligned with Mamdani’s political vision were performing strongly among Democratic voters.
Brad Lander Defeats Incumbent Dan Goldman
The third victory came in New York’s 10th Congressional District, where former New York City Comptroller Brad Lander defeated incumbent Representative Dan Goldman.
Election projections showed Lander receiving nearly 66% of the vote compared to Goldman’s 34%, making it the most decisive of the three contests.
The victory capped a remarkable night for candidates backed by Mamdani and highlighted growing support for progressive voices within the Democratic electorate.

Mamdani Celebrates Sweep
Following the results, Mayor Mamdani joined supporters and victorious candidates in celebrating the primary wins.
Speaking at Brad Lander’s election gathering, Mamdani praised the former comptroller and described him as a leader who represents a different approach to politics than voters have traditionally experienced.
The mayor’s appearance alongside the winning candidates underscored his central role in the campaigns and reinforced perceptions of his expanding influence in New York politics.
What Do the Results Mean for Democrats?
Political analysts view the victories as more than just local election outcomes. The results may offer clues about the direction Democratic voters want the party to take nationally.
The success of Mamdani-backed candidates suggests that progressive ideas continue to resonate with many Democratic primary voters, particularly in urban districts. At the same time, the defeats of incumbent lawmakers demonstrate a willingness among voters to support new faces and alternative political approaches.
As Democrats seek to regain or strengthen their position in Congress during the 2026 midterm elections, these races could become an important case study for campaign strategists across the country.
A Growing Force in Democratic Politics
The clean sweep by Mamdani-endorsed candidates marks one of the most significant demonstrations of his political influence since becoming mayor. By helping three candidates secure primary victories—including defeats of two sitting members of Congress—he has positioned himself as an increasingly important figure in Democratic Party politics.
Whether these victories represent a broader national trend or remain largely unique to New York will become clearer in the months ahead. However, the results have already sparked discussion about whether the coalition and messaging championed by Mamdani could serve as a model for Democratic candidates heading into the crucial midterm elections.
