Election results: Zohran Mamdani wins NYC mayor, Mikie Sherrill wins NJ governor

The Republican candidate wished Mamdani well as New York's new mayor but warned he will mobilize his supporters if the democratic socialist attempts to "implement socialism" and "render our police weak and impotent.'

"We're not only organizing, but we are mobilizing and we will become the mayor-elect and his supporters' worst enemies," said Sliwa, the founder of the Guardian Angels, the citizen safety patrol group he started 1979.

Sliwa also told a cheering crowd that "some of the most powerful people in the world" mobilized against his candidacy. Trump urged Sliwa voters to support Cuomo to help prevent a Mamdani victory.

House Speaker Mike Johnson put out a statement criticizing Mamdani and the Democrats after his historic win.

Johnson said Mamdani's win "cements" the Democratic Party's "transformation to a radical, big-government socialist party."

"Now, every House Democrat incumbent and candidate will co-own Mamdani's disastrous record in the 2026 midterms," he added.

Mamdani posted a short video on Bluesky after several outlets projected he would win the New York City mayoral election.

The video showed a subway door opening at the City Hall stop, with an announcement saying, "The next stop is City Hall."

She posted a short message on X thanking voters for choosing her to become New Jersey's next governor.

"It is the honor of my life to earn your trust to become this great state's 57th Governor," the Democratic candidate said. "I promise to listen, lead with courage, and never forget who I serve."
