Zohran Mamdani created a new anti-establishment playbook — in his use of social video, his focus on affordability and his position on Israel.

His assumed victory in New York City’s Democratic mayoral primary, trouncing the former governor Andrew Cuomo, was one of the biggest political upsets in years. And while the electorate in this case is pretty specific, I think it still points to some tectonic changes in Democratic politics.

My friend Chris Hayes, the host of MSNBC’s “All In With Chris Hayes,” came on the show earlier this year to talk about his book “The Sirens’ Call,” which is all about how social media and the new attention economy are shaping politics. So I wanted to bring him back for a sequel, to get “The Sirens’ Call” take on Mamdani’s victory, and Hayes’s insights as a born-and-raised New Yorker, with a deep feel for both the city’s politics and the broader Democratic Party.

This episode contains strong language.
