“If the election were tomorrow, he’d run away with it.”

That is how one prominent New York City financier put it to me on Monday, reacting to a new poll showing 33-year-old socialist Zohran Mamdani dominating the race for Gracie Mansion. That poll, released by progressive think tank Data for Progress, shows Mamdani, a first-term state legislator, crushing Andrew Cuomo, a former New York governor once believed to have White House potential.
