In the weeks since the primary, several prominent donors who had been supportive of Cuomo pledged their support to Adams in the general election, including billionaire hedge-fund managers Dan Loeb and Bill Ackman, both of whom have become so entwined with the Adams operation that they have helped vet campaign hires.

Running what was often described as a rose garden-style campaign, Cuomo limited his number of public appearances during the primary campaign and rare interactions with the press. In his new video, which clocked in at about 90 seconds, Cuomo walked the city streets taking selfies, shaking hands and chatting with New Yorkers.
