It's funny you say that when most of the NY state government backed Mamdani. Like 3 people is hardly a coordinated effort. I shouldn't have to know this since I don't live in NY either, at least I hope you don't given that Mamdani racked up important endorsements in state.
both things can be true. local national dems I mention have been abysmal and outright hostile to his campaign. Jeffries is a fucking joke and Gillibrand had an insane meltdown re Israel a month or so ago on a local radio program that got noticed. (shockingly, she apologized)
Gillibrand got yelled down by CA State party over Mamdani. I don't even think both things are true cause it's very clear that there is basically no coordinated effort happening unless you just ignore all the coordinated effort to get Mamdani the nomination. Like there isn't a coordinated conspiracy
