A closely watched Democratic primary in New York is becoming another test of whether the city’s progressive movement can turn Zohran Mamdani’s mayoral coalition into congressional power.
Darializa Avila Chevalier, a 32-year-old progressive organizer and public defense investigator, is challenging Rep. Adriano Espaillat in New York’s 13th Congressional District, which includes parts of Upper Manhattan and the Bronx. Espaillat, a five-term incumbent, chairs the Congressional Hispanic Caucus and has represented the district since 2017.
The race has drawn new attention because Avila Chevalier is backed by Mamdani, the progressive New York City mayor whose rise reshaped local Democratic politics. Mamdani has also endorsed other insurgent congressional candidates, including Claire Valdez and Brad Lander, as progressives try to challenge more established Democrats across the city.
Avila Chevalier is running on a left-wing platform that includes universal healthcare, stronger renter protections, campaign finance reform, a ban on congressional stock trading and abolishing Immigration and Customs Enforcement. She has also criticized what she calls establishment politics, arguing that long-serving officials have failed to address poverty, displacement and affordability in working-class communities.

Espaillat has pushed back by emphasizing experience and legislative results. At a recent candidate forum, he argued that getting things done in Congress requires more than academic credentials or activist energy. His supporters point to his long community ties, his leadership role in Congress and his ability to deliver federal resources for housing, education and infrastructure.
The district is heavily Democratic and deeply diverse, with large Latino, Afro-Latino and Black communities. Neighborhoods such as Harlem and Washington Heights have faced major affordability pressures, with residents warning that gentrification and rising costs are pushing longtime families out.
Avila Chevalier has argued that those conditions show the need for new leadership. She says Espaillat has been in public office for decades while many residents still struggle with housing, poverty and access to basic services.
The race has also become part of the national debate over Israel and U.S. foreign policy. Avila Chevalier has a history of pro-Palestinian activism, including work connected to student organizing at Columbia University. She has criticized AIPAC and big-money political spending, while opponents have questioned some of her past statements and positions on Israel.
Espaillat has received support from several Latino political leaders who argue that his record and seniority matter. A coalition of elected officials has praised him as a proven representative for the district and warned against replacing him with an untested challenger.
Still, the race appears competitive. An internal poll conducted for Justice Democrats by Data for Progress showed Avila Chevalier leading Espaillat 39% to 35% among likely primary voters, though internal polls should be treated cautiously because they are often released to shape momentum.
Mamdani’s endorsement could be a major factor. His campaign strength in parts of the district showed that progressive messaging on rent, affordability, policing and foreign policy can resonate with local voters. The question is whether that energy can transfer to a congressional primary against a well-known incumbent.
For progressives, a win would signal that Mamdani’s victory was not a one-off event but part of a broader leftward shift in New York Democratic politics. For establishment Democrats, holding the seat would show that experience, institutional power and community relationships still matter.
The primary is likely to be watched far beyond the district because it reflects a larger fight inside the Democratic Party: whether voters want experienced incumbents who know Washington or younger challengers promising a more confrontational politics.
Why It Matters
The NY-13 race matters because it tests the strength of New York’s progressive movement after Mamdani’s rise. A win for Avila Chevalier would be a major blow to the Democratic establishment, while an Espaillat victory would show that senior incumbents can still withstand left-wing challenges.
What Comes Next
Voters will decide whether to keep Espaillat or choose Avila Chevalier in the Democratic primary. Because the district is safely Democratic, the primary winner will likely be strongly favored in the general election.
