Quite possibly. Although we shouldn't overestimate the radical nature of Sanders. He called Hugo Chavez a 'dead communist dictator', for instance.
But yes, bit like here, where it seems some Labour MPs would rather the Tories in power than Corbyn.
And this is where I'd dispute a lot of what has been posted on here in the last couple of days where people are saying the liberals got it wrong. Taking Sanders to be an actual US liberal, which I think is fair, as opposed to Clinton, who by any objective measure really is rather right-wing, the forces that helped Clinton to the nomination were not in any way 'left'. They were anti-left. And they still beat Trump in the popular vote - also a mistake, I think, to overestimate Trump's success and popularity here: he won something like 46% of a 55% turnout. He achieved the popularity needed to win the election, but that's as much a reflection of the overall rotten nature of US democracy as anything else.
