Mayor Zohran Mamdani’s Endorsements Put Democratic Socialists to the Test in New York’s June 23 Primaries
6/23/2026, 7:56:16 PM
Core Event: Endorsements and Primary Stakes
New York City Mayor Zohran Mamdani has endorsed three Democratic-socialist candidates for the June 23, 2026 congressional primaries: former Comptroller Brad Lander in the 10th District, community organizer Darializa Avila Chevalier in the 13th District, and Assemblymember Claire Valdez in the 7th District. All three challengers face incumbent or establishment-backed opponents in districts that are safely Democratic in the general election.
Background & Context
Mamdani’s mayoral victory six months ago marked the first democratic-socialist win in a major U.S. city in a decade. His administration has pursued progressive policies such as a “pied-à-terre” tax and expanded free childcare. The endorsements arrive amid a broader wave of democratic-socialist successes in Seattle, Washington DC, Los Angeles and other cities, and ahead of the 2028 presidential primary.
Key Figures & Groups
- Zohran Mamdani – New York City mayor, Democratic Socialist (DSA).
- Brad Lander – Former city comptroller, challenger to Rep. Dan Goldman (10th Dist.).
- Darializa Avila Chevalier – Organizer and immigrant-rights activist, challenger to Rep. Adriano Espaillat (13th Dist.).
- Claire Valdez – Union organizer, challenger to the candidate endorsed by retiring Rep. Nydia Velázquez (7th Dist.).
- Incumbents – Rep. Dan Goldman, Rep. Adriano Espaillat (Chair of the Congressional Hispanic Caucus), and the retiring Rep. Nydia Velázquez.
- Supporting figures – Sen. Bernie Sanders, Gov. Kathy Hochul, Rep. Hakeem Jeffries, and the Democratic Socialists of America.
Data & Statistics
New York has roughly 13.4 million registered voters, including about 6.4 million Democrats. Early-voting sites reported 107,000 ballots cast before Election Day. The 12th District primary has attracted $26 million in advertising, while the 13th District race has drawn attention for Avila Chevalier’s past social-media posts.
Why It Matters / Impact
Success for Mamdani-backed candidates could demonstrate the electoral viability of democratic-socialist platforms in the state’s “blue” districts and influence the party’s strategy for swing districts in the 2028 presidential cycle. A defeat of incumbent Espaillat, chair of the Congressional Hispanic Caucus, would be cited by national strategists as a signal of shifting voter preferences.
Official Statements & Responses
Mamdani told a rally with Sen. Sanders that the Democratic Party “has seen its job as explaining why we cannot instead of showing how we can,” urging voters to act now. Espaillat responded on X that Avila Chevalier’s “extreme positions” make her “unfit for office.” Velázquez warned that “I am not going to allow DSA to define who is progressive and who is not.” Bernie Sanders publicly endorsed Lander and Valdez, emphasizing a “people-first” agenda.
Criticism & Opposition
Jewish community leaders condemned Mamdani’s description of AIPAC as part of a group of “monsters,” labeling the language antisemitic. Latino leaders expressed concern over Avila Chevalier’s prior calls to “abolish police” and “question Israel’s right to exist,” noting that such statements could be weaponized by opponents. Velázquez criticized Mamdani for backing Valdez over her endorsed successor, Antonio Reynoso.
On-the-Ground Reports
Mamdani voted early at the Metropolitan Museum of Art and appeared at campaign rallies for all three endorsed candidates. Television ads featuring Mamdani and the candidates aired during Knicks playoff games.
Conflicting Reports & Gaps
An Emerson College/Pix11 poll shows a tight race in the 7th District, while other polls are unavailable. No public polling has been released for the 13th District, leaving the impact of Avila Chevalier’s controversy difficult to gauge.
