Darializa Avila Chevalier defeated five-term incumbent Adriano Espaillat in the Democratic primary for New York’s 13th congressional district on June 23, 2026 [1], [2].
The victory represents a significant shift in power within the city's political landscape, signaling a move away from the Democratic establishment and toward a socialist-aligned agenda.
Chevalier, a 32-year-old [1] Ph.D. student, secured the nomination with the support of New York City Mayor Zohran Mamdani [1], [2]. The 13th district covers portions of the Bronx and Upper Manhattan [1], [4].
This win was part of a broader political project led by Mamdani. His strategy utilized Democratic Socialist (DSA) backing to challenge the influence of the incumbent Hispanic caucus chair and the existing party hierarchy [1], [2], [3].
Espaillat had held the seat for five terms [1]. His defeat marks one of the most prominent losses for established Democratic leadership in the recent primary cycle.
Chevalier is now positioned to represent the district in the general election. Her campaign focused on shifting power dynamics within the city's governance, a goal shared by the socialist allies who swept several NYC primaries this week [2], [3].
“Darializa Avila Chevalier defeated five-term incumbent Adriano Espaillat”
The defeat of a long-term incumbent by a young, socialist-backed candidate indicates a growing appetite for ideological shifts within New York's Democratic base. By leveraging the organizational power of the DSA and the visibility of Mayor Mamdani, the win suggests that the 'establishment' wing of the party is losing its grip on urban districts in favor of a more progressive, socialist-leaning coalition.
