Voting starts on Saturday for one of America’s biggest and most prominent political positions. How did Zohran Mamdani, the Democratic nominee, emerge as the frontrunner to be the next mayor of New York, despite being virtually unknown at the start of his campaign?

Sarah, Justin and Anthony look in more detail at his policies, and in particular the centrepiece of his campaign around the cost of living. Mamdani says he will make New York more affordable, by increasing housing stock, raising taxes for the rich and bringing down the cost of rent. How realistic are his promises and how much could it matter if he can’t deliver? We also unpack his views on Israel and Gaza, and how his views on Gaza could affect the Jewish vote in New York, the biggest outside of Israel.

We get an inside track on Mamdani’s campaign from Eric Lach, staff writer at the New Yorker, who has been following him on the campaign trail, from before he won the primaries, to having dinner at Mamdani’s apartment in Queens. He also shares his views on how Mamdani will handle the NYPD, the country’s largest police department, after calling for the police to be defunded in 2020.

Donald Trump has made clear he thinks Mamdani is a radical left communist, so how might he handle the US president if he is elected as mayor? And how might Donald Trump target New York in return?
