As I've stated before, Trumpism is something that lives and dies with Trump, but Bernie's ideas are more palatable than he is. Its important here to make a distinction between Bernie supporters and Trump supporters. Yes, both are rabid and highly defensive. But whereas many Trump supporters seem to like Trump for how much he shitposts and causes chaos, Bernie supporters like his actual policies more than his "style". Trump supporters like Trump as a person, whereas if I'm being completely honest, Bernie supporters just want him to make their lives better and then fuck off. Even in the worst case scenario, he's pushed once "radical" ideas like singlepayer healthcare into the national conversation.
I don't think anybody sees Bernie as a savior like they viewed Trump. Bernie getting elected is simply the first step, not the endgame like with "God Emperor" Donnie. The economic left is extremely pragmatic and cynical about the state of things, and despite fervently supporting Bernie they don't see him as a magical messiah. He's there to serve one purpose only: push America's economic policies leftward. If Bernie is elected most leftists will simply sigh in relief and unclench their spincters. Then the real work begins.
