Live updates: New York primaries, Mamdani-backed Lander, Valdez and Chevalier will win
Darializa Avila Chevalier, a democratic socialist and public defender investigator, is projected by CNN’s Decision Desk to win the Democratic primary in New York’s 13th Congressional District. She defeated incumbent Rep. Adriano Espaillat in a race that pitted Mayor Zohran Mamdani’s progressive wing against the establishment support of House Minority Leader Hakeem Jeffries.
Why did Darializa Avila Chevalier defeat Rep. Adriano Espaillat?
Chevalier’s victory stems from a growing wave of left-wing primary challengers targeting Democrats they describe as too establishment-friendly. According to CNN, her campaign was bolstered by the endorsement of New York City Mayor Zohran Mamdani, a democratic socialist.

The race served as a direct test of Mamdani’s political influence. In a strategic break from party leadership, Mamdani backed Chevalier while House Minority Leader Hakeem Jeffries supported the incumbent, Espaillat. This split highlighted a deepening rift within the city’s Democratic infrastructure over campaign strategy and policy direction.
What controversies marked the NY-13 primary race?
Chevalier’s path to victory wasn’t without obstacles. Reporting from CNN’s KFile revealed that the candidate had deleted social media posts containing several controversial positions. These posts included support for abolishing police, prisons, and borders, as well as statements calling into question Israel’s right to exist.
Further scrutiny focused on Chevalier’s presence at a Pro-Palestinian rally on October 8, 2023, the day following the Hamas attacks. These revelations nearly derailed her upset bid, yet they failed to stop her momentum among the district’s progressive base.
How does this win reflect trends in the Democratic Party?
The contest in NY-13 encapsulates a broader clash between the Democratic “old guard” and a new class of progressive challengers. According to CNN, this divide is driven by three primary catalysts: affordability policies, US relations with Israel, and internal campaign strategies.
While established leaders like Hakeem Jeffries prioritize party cohesion and traditional legislative paths, challengers like Chevalier—a 32-year-old doctoral student—represent a shift toward democratic socialist ideals. This victory suggests that the “establishment” label has become a liability in certain urban districts where voters are demanding more radical policy shifts.
What happens next for New York’s 13th District?
As the projected winner of the Democratic primary, Chevalier now advances to the general election. Given the district’s heavy Democratic lean, she is considered the favorite to win the seat. If elected, she will join a growing contingent of democratic socialists in Congress, potentially shifting the caucus’s approach to policing and foreign aid.
