Zohran Mamdani's surge to the top in New York City's Democratic mayoral primary came with the help of an army of volunteers who set a goal of knocking on 1 million doors to get votes.

Sources told CNN that Cuomo's team believes the general electorate could be more receptive to his candidacy than primary voters.

Zohran Mamdani declared victory in New York City’s Democratic mayoral primary Tuesday night after Andrew Cuomo conceded the race in a stunning upset. Mamdani is a progressive upstart who was virtually unknown when the contest began built a substantial lead over the more experienced but scandal-scarred former governor.
