In the poll by Slingshot Strategies, first reported by the New York Post, Mamdani has 36 percent of the vote compared to former New York Governor Andrew Cuomo 's 27 percent and current New York City Mayor Eric Adams' 14 percent. Republican candidate Curtis Sliwa landed 16 percent of the vote and independent candidate Jim Walden received 2 percent.

A new Yahoo/YouGov survey finds that about twice as many U.S. adults say they would vote for a candidate with Mamdani’s platform (50%) than say they would not (26%). Could it be a blueprint for Democrats elsewhere?

Mr. Mamdani’s victory upended city politics and reverberated nationally. He relied on a memorable message, charisma and a strong ground game.
