Former New York City Comptroller Brad Lander defeated incumbent Rep. Dan Goldman in the Democratic primary for New York's 10th congressional district, according to NBC News projections. The race, which centered on progressive versus establishment credentials, saw Lander gain late momentum with backing from labor-aligned progressive groups. President Donald Trump celebrated the outcome on Truth Social, calling Goldman a "weak and pathetic" figure who was "finally GONE."
Goldman, a first-term congressman known for his role in Donald Trump's first impeachment, had positioned himself as a centrist focused on institutional stability. Lander, a former citywide official with deep ties to organized labor and tenant advocacy groups, campaigned on housing affordability and progressive economic policies. The contest splintered the Democratic party's labor union alliance, as CNBC noted some unions broke ranks to support Lander's insurgent bid.
Trump's explicit endorsement of Lander's victory injected unusual cross-party dynamics into the race. The former president wrote on Truth Social that voters "didn't like him illegally targeting President TRUMP," referring to Goldman's work as lead counsel for Democrats during the 2019-2020 impeachment proceedings. The Hill reported Trump calling Goldman a "jerk" in his social media posts.
The primary result reshapes the electoral landscape in New York City's political corridor, which includes parts of Manhattan and Brooklyn. Exit polling suggested that voters prioritized local economic concerns — particularly housing costs and inflation — over national impeachment politics. Political analysts noted the outcome could signal brewing intraparty tensions ahead of the 2026 midterms, as progressive challengers continue testing incumbents in safe Democratic districts.
