The democratic socialist promised free childcare and buses and a rent freeze – can he deliver before New Yorkers lose patience?

After more than a year of repeating ambitious promises about freezing rent and making childcare free, Zohran Mamdani will wake on Wednesday with a daunting task ahead of him: make those things reality for New York City.

The 34-year-old democratic socialist ran New York’s most ambitious mayoral campaign in years, attracting hundreds of thousands of supporters with bold promises to make the largest US city affordable.

It was a campaign that made Mamdani a global sensation and invigorated many New Yorkers like never before, attracting almost 100,000 volunteers. Mamdani rejuvenated the left beyond New York’s borders, encouraging other progressives to run for office across the US, and could yet influence the Democratic party ahead of next year’s midterm elections.

The flip side, however, is clear: the residents of New York have had their hopes set incredibly high, and now Mamdani has to deliver.
