Who is Darializa Avila Chevalier, Mamdani-backed winner of New York House primary?

One of the biggest upsets in Tuesday night’s primaries came in New York’s 13th Congressional District, where Darializa Avila Chevalier, a 32-year-old democratic socialist, managed to beat incumbent Rep. Adriano Espaillat, 71, who was backed by establishment Democrats.

Chevalier, a doctoral student in sociology at the City University of New York, secured 49.4% of votes in the district — which encompasses upper Manhattan, Harlem and parts of the Bronx — defeating Espaillat, who received about 46% of the votes after representing the district for nearly a decade, according to The Associated Press. She now advances to the November general election, which she is presumed to win in the solidly Democratic district.

Chevalier’s primary win marks a major win for the Democrats’ left-wing flank that backed her, including New York City Mayor Zohran Mamdani, who endorsed Chevalier last month during a joint interview on MS NOW’s “The Briefing with Jen Psaki.”

Here is what to know about Chevalier and the platform she campaigned on.

She has no previous experience in politics

Prior to her congressional campaign, Chevalier had never run or held elected office. But she has been involved with advocating for issues that became political flashpoints, including helping organize the pro-Palestinian encampments at Columbia University, according to her biography on the website of the Justice Democrats, the progressive group that recruited her to run.

The daughter of Dominican immigrants, Chevalier also worked as an organizer for Families for Freedom, a New York City group that assists immigrants facing deportation.

Chevalier earned a bachelor’s degree in Middle Eastern studies from Columbia University in 2016 and later worked as a paralegal, according to her LinkedIn.

Chevalier faced scrutiny during her campaign over previously articulated stances and incendiary comments, including her appearance at a Times Square rally the day after Hamas’ attack on Israel on Oct. 7, 2023, where attendees reportedly suggested the attack was justified.
