The Zohran Mamdani method can work beyond New York. Take the fight to the right | Aditya Chakrabortty

For too long, the centre has been adopting the language of the right but deploying it with greater civility - to disastrous ends

Zohran Mamdani was forged in the era of Donald Trump. He came to socialism through watching Bernie Sanders run for the US presidency in 2016, in the contest that ultimately gave us Trump I. Last November, a few days after the election of Trump II, he asked voters why they'd backed that guy. The conversations prepared Mamdani in his battle for New York, and the film of them reveals so much about the politics of this era that it repays watching.

Those of us schooled in the tactics of Bill Clinton and Tony Blair might roll our eyes at yet another listening exercise", starring a powerbroker and his retinue in some beautifully lit hall, but this is no such thing. Here stands an unknown on a street corner in the Bronx, waving a placard as doughtily as a Seventh-Day Adventist. Rather than read off a Rolodex of platitudes, this politician sees his public - some of whom look a little like him, yet whose faces and bodies are etched with the strains of the city. Never having spoken to power, even a lowly state assemblyman such as Mamdani, they talk of lives made smaller and shorter in an economy where the daily basics are too costly. Politics has failed them, so they consider politicians to be failures.
