Andrew Cuomo is demanding that his opponent in New York City’s mayoral race, Zohran Mamdani, vacate his rent stabilized apartment, while pushing a longshot proposal that would bar other middle-class renters from accessing much of the city’s housing.

Zohran Mamdani, the Democratic nominee for New York City mayor, launched a tour Monday of the city’s five boroughs with a central message linking former Gov. Andrew Cuomo to President Donald Trump.

The attacks in the New York City mayor’s race may have veered into the personal, but they also reflected a larger debate on who should benefit from government regulation of housing costs.
