Schumer already did a kind of shy endorsement of Mamdani, after that the others politicians don’t have much room to stab the party in the back. The problem here are the donors; oligarchs are pissed.

My current bet would be that Cuomo will leave his name in the ballot out of spite but not really campaign, and lots of right wing Democrats will stay silent, while the oligarchs will try to resurrect Adams’ political career by throwing money at it (may all their donations burn into a pile of useless ash)
