Former New York City Comptroller Brad Lander defeated incumbent Democratic Rep. Dan Goldman in New York’s 10th Congressional District Democratic primary on Tuesday, delivering a major upset in one of the state’s closely watched congressional races, as reported by The Gateway Pundit.

With an estimated 39% of the vote counted, Lander held a commanding lead over Goldman, according to election results reported Tuesday night. The tally showed Lander receiving 19,702 votes, or 62.2%, compared to Goldman’s 11,996 votes, or 37.8%.

Lander entered the race with support from New York City Mayor Zohran Mamdani, whose endorsement helped elevate the former comptroller’s campaign among progressive voters.

The victory marks another significant win for the city’s increasingly influential left-wing political bloc.

Goldman, who was first elected to Congress in 2022, was backed by Kathy Hochul during the primary campaign. Despite receiving support from the governor, Goldman was unable to overcome Lander’s momentum as voters headed to the polls.

The race drew national attention because of Goldman’s high-profile role during President Donald Trump’s first impeachment proceedings.

Before entering Congress, Goldman served as lead majority counsel during the 2019 impeachment inquiry against Trump. He later served as lead counsel to the impeachment managers during the Senate impeachment trial.

Goldman’s political profile rose sharply during those proceedings, making him one of the most recognizable Democrats elected during the 2022 midterm cycle.

His defeat now removes one of the most prominent impeachment-era figures from Congress.

Lander also received support from Sen. Bernie Sanders and Mamdani, endorsements that helped consolidate progressive support behind his campaign.

The coalition proved effective against Goldman, whose backing from establishment Democratic figures was not enough to secure another term.

The contest highlighted ongoing divisions within New York’s Democratic Party, where progressive candidates have increasingly challenged incumbents aligned with more traditional party leadership.

Lander’s victory adds to a series of primary contests that have showcased the growing influence of progressive activists and organizations in the city.

Goldman’s campaign also received support from pro-Israel groups during the race.

The district, which includes parts of Brooklyn and Manhattan, has seen significant political debate surrounding Middle East policy and related issues, creating another point of contrast between the candidates.

The result represents one of the most notable Democratic primary upsets of the 2026 election cycle.

A sitting member of Congress with statewide Democratic support, national name recognition, and a prominent role in one of the most consequential political battles of the Trump era was defeated by a challenger who successfully united progressive voters behind his campaign.

With the primary now decided, Lander is positioned to become the Democratic nominee for New York’s 10th Congressional District as the general election campaign begins.

Dan Goldman, once known nationally for his role in the impeachment effort against President Trump, will leave Congress after a single term following Tuesday’s decisive primary defeat.
