Zohran Mamdani released a video of himself interviewing people on the street in Queens and the Bronx who had voted for Donald Trump in the presidential election the previous week. It was one of the first of the viral posts that propelled him into the spotlight and ultimately helped him all but capture the Democratic nomination for mayor of New York.

Many details of Zohran Mamdani’s stunning win in New York City’s Democratic mayoral primary on Tuesday are yet to become clear, including exactly how many voters ranked him first and whom he will face in November’s general election.
