He could probably still clear fifty-plus percent of the vote. The problem I see....the Cops and Firemen union will be totally against him from this point on out. The teachers union might still side with him...at least until he does some budget cuts. The anti-frisk crowd will also stick with him...until criminal statistics go sour.
Too many of the public sector employees aren’t even NYC voters; who would make so much money and still live in that Third World hole? They vote in Westchester & Orange counties, or out on the island...
The mutants living in the city itself? Yes, they’d probably elect him again in a heartbeat; those are the freaks holding the signs.
