NYC Mayor’s Machine Steamrolls Democratic Royals

New York’s Democratic Party just got a socialist makeover — and one of the loudest anti-Trump voices in Congress paid the price at the ballot box.

Story Highlights

Socialist-backed candidates swept New York congressional primaries on June 23, 2026, ousting two Democratic incumbents.
Rep. Dan Goldman — best known as lead counsel in Trump’s first impeachment — lost his seat to a candidate backed by socialist NYC Mayor Zohran Mamdani.
Mamdani, who won the NYC mayor’s race in 2025, is building a political machine that is pulling the Democratic Party sharply to the left.
Analysts warn that socialism’s national appeal sits around 30%, raising questions about whether this leftward shift will hurt Democrats in general elections.

Goldman Ousted After Riding Anti-Trump Wave

Rep. Dan Goldman built his national profile as the lead counsel during Donald Trump’s first impeachment. He became a fixture on liberal media and a loud Trump critic. But on June 23, 2026, New York voters ended his congressional career. Former city Comptroller Brad Lander — endorsed by socialist Mayor Zohran Mamdani and Senator Bernie Sanders — defeated Goldman in the Democratic primary for New York’s 10th Congressional District.^[4]

Goldman’s defeat was not just about personality. It centered heavily on the Israel-Gaza conflict. Goldman refused to call Israel’s actions in Gaza genocide, a position that put him at odds with the progressive base that now drives New York City Democratic primaries. His challengers took a harder anti-Israel line, and primary voters rewarded them for it.^[9]

Mamdani’s Machine Rolls Through NYC

Mamdani won the NYC mayor’s race in November 2025 with 50.78% of the vote, defeating both former Governor Andrew Cuomo and Republican candidate Curtis Sliwa.^[1] His win was powered in large part by young voters — 75% of voters aged 18 to 29 backed him.^[2] He also won 61% of precincts with mostly Black residents and 57% of precincts with mostly Hispanic residents.^[1] That coalition gave him a strong base to influence the 2026 primaries.

Beyond Goldman’s race, Mamdani’s endorsed candidate Darializa Avila Chevalier defeated incumbent Rep. Adriano Espaillat in a neighboring district.^[4] Progressive Claire Valdez also won the 7th District primary, defeating the candidate backed by the outgoing incumbent.^[5] All three of Mamdani’s picks won. The Democratic establishment — including Governor Kathy Hochul, House Minority Leader Hakeem Jeffries, and retiring Rep. Nydia Velazquez — backed the incumbents and lost.

The Bigger Picture: Democrats Lurching Left

This is not a one-time event. From Maine to California, progressive and centrist Democrats have clashed in primaries throughout 2025 and 2026. The left has maintained an edge in urban races, while centrists have held on in Texas and North Carolina. Analysts at CNN note that neither side has scored a decisive national victory, but progressives are gaining momentum in the cities where Democratic primaries are decided.^[14]

Backed by Bernie Sanders and Zohran Mamdani, Brad Lander just pulled off a major Democratic primary upset.

For conservatives, the takeaway is clear. The Democratic Party’s loudest anti-Trump voices are being replaced by candidates who back socialist economic policies, oppose Israel, and align with the Democratic Socialists of America. Polling shows socialism holds only about 30% national support, meaning this leftward lurch could make Democrats easier to defeat in general elections outside deep-blue cities. Republicans would be wise to watch — and use — this split heading into the 2026 midterms and beyond.
