In a Rolling Stone interview with Charles Young (from the early 90s, if mem serves), Noam said that if the Dems nominated Charlie McCarthy (a ventriloquist puppet from radio's Golden Age, for those unaware), he'd vote for him on the grounds that the Repub candidate would be worse for those without power. Not that the Dem would be great and noble, far from it, but at least there'd be some breathing room and a chance to organize and push ahead, as opposed to reclaiming lost ground from the Repubs.
So, Chuck, Noam's "endorsement" is nothing new, and is only a minor part of his voluminous output.
