Democrat Rep. Dan Goldman LOSES Primary To Mamdani Backed Candidate

New York Democrats were torched by Progressives in Tuesday’s primaries.

One of the biggest upsets was Democrat Rep. Dan Goldman losing to Brad Lander who is a former member of the Democratic Socialists of America.

Lander was endorsed by both Senator Bernie Sanders and New York City Mayor Zohran Mamdani.

The race was not even close!

Take a look:

Fox News reported more on Goldman’s defeat:

Former New York City Comptroller Brad Lander, a former Democratic Socialists of America member backed by Sen. Bernie Sanders, I-Vt., and New York City Mayor Zohran Mamdani, defeated Rep. Dan Goldman in Tuesday’s Democratic primary for New York’s 10th Congressional District.

Lander, who describes himself as a “liberal Zionist,” ousted Goldman in a head-to-head primary in one of the nation’s bluest House seats. The district spans Lower Manhattan and parts of western Brooklyn, taking in liberal neighborhoods from Greenwich Village and the Lower East Side to Brooklyn Heights, Park Slope and Sunset Park.

The result marked a victory for the city’s ascendant progressive wing, with Sanders and Mamdani helping Lander topple Goldman, a former federal prosecutor who served as lead counsel during the first impeachment inquiry into President Donald Trump.

Goldman was first elected to Congress in 2022 after winning a crowded Democratic primary in the newly redrawn district.

Lander wasn’t the only progressive candidate who was endorsed by Mamdani and won.

Darializa Avila Chevalier defeated five-term incumbent Adriano Espaillat in New York’s 13th congressional primary.

BBC reported more on Mamdani’s clean sweep in endorsements:

US congressman Dan Goldman has been defeated in a New York primary election, capping a clean sweep for candidates backed by New York’s democratic socialist Mayor Zohran Mamdani as he seeks to tilt the Democratic Party to the left.

Goldman was beaten by progressive challenger Brad Lander in New York’s 10th congressional district in a contest that laid bare the party’s divisions over the Israel-Gaza war.

Lander has accused Israel of genocide in Gaza. Goldman, a two-term incumbent, was backed by pro-Israel groups.

Two other candidates, both democratic socialists endorsed by Mamdani, won their primary races on Tuesday, in a boost for the party’s left wing in America’s largest city.

Assemblywoman Claire Valdez unseated Brooklyn Borough President Antonio Reynoso in the 7th district.
Darializa Avila Chevalier, a doctoral student who has joined pro-Palestinian protests at Columbia University, won her race in New York’s 13th district.

Lander, who was also endorsed by Vermont’s democratic socialist Senator Bernie Sanders, easily beat Goldman by 65.7% to 34.1%, with most votes counted.

The left-wing former New York City comptroller’s bid against Goldman, who was first elected to Congress in 2022, was seen as a test of Mamdani’s political influence.
