In a race that was seen as a proxy war for different visions of the progressive future, democratic socialist Claire Valdez is projected to win the Democratic nomination to represent New York’s 7th Congressional District. “When working people come together, we can move mountains,” Valdez said in her final ad of the campaign.
Valdez’s Background and Campaign
Valdez, a relative newcomer to politics who has served as a member of the New York State Assembly since 2025, had touted her background as a union organizer as giving her the experience needed to represent the district over the other main contenders, Brooklyn Borough President Antonio Reynoso and City Councilor Julie Won. Her win comes as a victory for New York City Mayor Zohran Mamdani, who backed the little-known assemblywoman as part of a push to support allies for Congress.
The victory speaks to the power of the heavily blue district nicknamed the “commie corridor,” for its base of young, left-leaning, and politically passionate voters in a primary that became seen as a battle between Democratic factions. The Democratic nomination for NY-7 was hotly contested after its long-time representative, Democrat Nydia Velázquez, the first Puerto Rican woman elected to Congress, announced that she would not seek reelection in 2026.
Endorsements and Platforms
Besides Mamdani, Valdez was endorsed by leading figures such as Vermont Sen. Bernie Sanders, while Reynoso touted backing from fixtures including Velázquez herself, the Working Families Party, and New York Attorney General Letitia James. While both candidates ran on substantially similar, progressive platforms — central issues for both were addressing New York’s housing crisis, abolishing ICE and “Medicare for All” — the split in endorsements positioned the race as both a test of Mamdani’s political influence after his mayoral win, and a competition for the changing face of the district.
The heavily-blue area covers a racially and economically diverse swath of Brooklyn that has been a hotbed of gentrification in recent years. Opponents had characterized Valdez, who was born in Texas, as emblematic of the transplants that have both gentrified parts of the district and amplified its political caché. Reynoso, meanwhile, had highlighted his status as a native-born New Yorker and child of immigrants to establish his credentials, and pointed to his long experience in politics as reasons for voters to back him.
Election Dynamics and Mamdani’s Role
In the days leading up to the election, polls showed Valdez and Reynoso in a neck-and-neck race, with Won a distant third. The weekend before Election Day, Mamdani accompanied Valdez to meet voters in the district, leveraging his popularity — a recent poll showed 78% of voters in the district approved of him — in her support.
Valdez’s win underscores the influence of Mayor Mamdani, who has been a rising star in New York politics. The race also highlighted the ongoing debate within the Democratic Party between establishment figures and more progressive, grassroots candidates. With the general election in a safely Democratic district, Valdez is widely expected to become the next representative for NY-7.
