President Trump reacted to the results Tuesday night in a post on Truth Social, quoting anonymous pollsters: “‘TRUMP WASN’T ON THE BALLOT, AND SHUTDOWN, WERE THE TWO REASONS THAT REPUBLICANS LOST ELECTIONS TONIGHT,’ according to Pollsters.”

Later, Trump reiterated calls for congressional Republicans to “terminate the filibuster” and “pass voter reform.” And he capped off the evening with a cryptic post: “…AND SO IT BEGINS!”

White House deputy chief of staff Stephen Miller, who has been described as an architect of Trump’s anti-immigrant agenda, appeared to rationalize Mamdani’s victory in New York City by posting on X a screenshot of a statistic that says, “Almost 50 percent of New Yorkers live in family households with at least one immigrant.”

Other Republicans reacted to Mamdani’s win with fear-mongering language similar to that which failed in the campaign opposing the 34-year-old Democrat.

House Speaker Mike Johnson (R, La.) claimed: “Democrats in New York City have chosen a true extremist and Marxist, and the consequences will be felt across our entire nation.” Johnson posted on X that “Zohran Mamdani’s election cements the Democrat Party’s transformation to a radical, big-government socialist party,” and that while “Mamdani’s extreme agenda is the future of the Democrat Party,” the GOP “will never allow it to be the future of America.”

House Majority Leader Steve Scalise, (R, La.) echoed Johnson on X, saying that New York City has “officially fallen to the radical socialist wing of the Democrat party and New Yorkers will pay the price.”

Rep. Randy Fine (R, Fla.) posted on X: “Legal immigrants who hate America elected a Communist Muslim Jihadist. New York City has fallen. America is next if we don’t stop it.”

“Bread lines about to be a real thing in New York. Congrats,” Rep. Nancy Mace (R, S.C.) posted.

Texas Gov. Greg Abbott posted, “Join me for a moment of silence for NYC. Thoughts & prayers.”

Florida Gov. Ron DeSantis, speaking to Fox News Tuesday night as results came in, said that Mamdani will “make the de Blasio reign look like the ‘golden age,’” referring to the unpopular Democratic former Mayor Bill De Blasio.

Sen. Rick Scott (R, Fla.) invited those disappointed with Mamdani’s victory to move. “Florida has welcomed those fleeing communist and socialist regimes for decades,” Scott posted. “Tonight is no different—Florida will welcome all freedom-loving New Yorkers!”

Rep. Mike Lawler (R, N.Y.) reposted comments he made about Mamdani on Fox News earlier Tuesday. “You have an avowed socialist engaged in Marxist theory talking about freezing the rent, banning private property ownership, seizing the means of production, defunding the police, shutting down prisons, legalizing prostitution, oh, and raising taxes by $9 billion in the financial capital of the world,” he said, before alluding to 2026 midterm elections: “Yeah, this is not going to go well in the suburbs of New York next year.”

Rep. Elise Stefanik (R, N.Y.), who is reportedly set to launch a bid for New York governor, blamed incumbent Democratic Gov. Kathy Hochul, who endorsed Mamdani, for Mamdani’s victory, saying that under Hochul, New York City “has now fallen to a pro-Hamas, Defund the Police, Tax Hiking, Antisemite Jihadist Communist.”

“And instead of standing up for hardworking New York families, Kathy Hochul proved once again that she is truly the Worst Governor in America with her desperate endorsement of Commie Mamdani,” Stefanik posted on X.

The National Republican Congressional Committee, which supports GOP members in Congress, said in a statement that the Democratic Party “has surrendered to radical socialist Zohran Mamdani and the far-left mob who are now running the show.” According to NRCC spokesperson Mike Marinella, Democrats have “proudly embraced defunding the police, abolishing ICE, taxing hard-working Americans to death, and replacing common sense with chaos. Every House Democrat is foolishly complicit in their party’s collapse, and voters will make them pay in 2026.”
