New York: Mamdani-Backed Candidates Win Democratic Primaries

The Democratic primaries in New York produced results that reconfigure the party’s political map. The candidates backed by Mayor Zohran Mamdani secured victories in two key contests, consolidating their influence within the progressive wing. Assemblywoman Claire Valdez and former Comptroller Brad Lander won this Tuesday. Both will now seek a seat in the U.S. House of Representatives in the general elections. NBC News and Associated Press projections confirmed the results. The victory represents a boost for the progressive wing of the Democratic Party in one of its electoral strongholds.

Victory in Key Districts

Claire Valdez achieved a significant victory in New York’s seventh congressional district. The constituency encompasses areas of Brooklyn and Queens, with a diverse electoral base. Her main rival was Antonio Reynoso, current president of Brooklyn borough. Reynoso had the backing of prominent figures within the party and political organizations. Among his supporters was outgoing Congresswoman Nydia Velázquez. The historic legislator decided not to seek reelection after more than three decades in Congress. Velázquez publicly endorsed Reynoso in U.S. media. She was also supported by the Working Families Party, which had previously backed Mamdani’s candidacy. Despite these endorsements, Valdez prevailed with a campaign aligned with progressivism. She received support from the Democratic Socialists of America and Senator Bernie Sanders.

The Weight of Mamdani’s Endorsement

Mayor Zohran Mamdani played a decisive role in these primaries. His endorsement of Valdez and Lander drew a clear line within the Democratic electorate. The victory of both candidates reinforces his political leadership in the city. It also demonstrates the mobilization capacity of the progressive bloc. In parallel, Brad Lander prevailed in the tenth congressional district. He defeated Congressman Dan Goldman, who was seeking a third consecutive term. Goldman had held the seat since 2023 and had legislative experience. However, his position on international issues influenced the outcome. His support for Israel and ties to the Israeli lobby generated criticism. These factors ultimately weakened his candidacy against Lander.

Israel, Central to Internal Dispute

The contest in the tenth district reflected tensions within the Democratic Party. The debate over policy toward Israel was one of the main axes. Analysts considered this election a test of the weight that issue carried with voters. The results suggest a shift in the sensitivity of some voters. Brad Lander distanced himself from Goldman during the campaign. He stated he had not received funding from the Israeli lobby and adopted a critical stance on the Gaza conflict. The former comptroller also explained his departure from the Democratic Socialists of America. He cited disagreements with the organization following Hamas attacks in 2023.

«I found it appalling,» he stated in a debate, referring to a demonstration organized by the group. His statements revealed tensions within progressivism itself. Despite that distancing, Lander maintained support in key sectors. He was the only candidate backed by Mamdani with prior DSA endorsement.

A New Balance in the Democratic Party

The results of these primaries show a realignment within New York’s Democratic Party. The advance of progressive figures reinforces a trend consolidating in recent years. The defeat of candidates with traditional backing indicates a shift in voter priorities. Issues such as foreign policy, social justice, and local representation gain weight. Valdez’s case is particularly symbolic. Her victory comes in a district historically linked to established leadership. Furthermore, Nydia Velázquez’s retirement marks the end of an era. She was the first Puerto Rican woman to reach Congress and an influential figure for decades. For his part, Goldman’s loss reveals difficulties for certain moderate profiles. The Democratic base appears to be leaning toward more defined positions on sensitive issues.
