If you limit the focus to what happens, yeah, that's true. What will happen is nothing.
If you widen the focus to what does not happen, that Zohran fails to garner support from outside deep blue areas, all of the sudden, these sorts of things become much more important.
The status quo is that despite having the best set of material policies, progressives fail to catch on with the general public. It's not super mysterious why. The idpol is fractious. If Mamdani is to change that status quo, he really has to avoid playing it and there he is so far falling short.
Like, one of the great political questions of our era is, roughly, "will the public accept our social views if we give them a better material deal?", and it's been asked by the bouge. They have their answer, if they care to honestly appraise election results: no.
They will NBD it for now because said ideology is far too deeply entrenched, but it is limiting, and unless Mamdani can rebrand to a vision of leftism unreliant upon it, yeah, he'll be marginal and perhaps eventually vulnerable in NYC itself(as his promises fail to materialize without support from higher offices he cannot capture with present vibes).
