Bypassing a few posts of lies about Bernie supporters (but oh no it's the Bernie supporters who are bad people, not the perfect angelic Biden supporters who keep lying about them!) to get to a presumably honest question about us...
Re: Sanders and his supporters...
I'd be curious about how they would react if he won the Democratic nomination but lost the general election.
...would they try to argue that it was still somehow the fault of mainstream/establishment democrats?
Well, it would be, in the sense that any election loss is always partially the "fault" of people who might have been expected to vote for that candidate but didn't... just the same as a Biden loss would be partially the "fault" of Democrats who didn't vote for Biden, and a Trump loss would be partially the "fault" of Republicans who didn't vote for Trump, and a Yyblax of Zebulon loss would be partially the "fault" of members of the Vonla'br'ugk Party who didn't vote for Yyblax...
I don't think I get what point anybody would be making by pointing out such a basic universal thing, though, or what point you would even wonder if we were making. You certainly can't be saying this would be a difference between Bernie and Biden supporters, can you? I see Biden supporters already starting in on that, and he hasn't even lost yet.
Rather than admitting those "lost tribes" of left-wing voters never existed...
Really, we're back to the "lost tribes" mantra now? I thought that might have gone the way of the "we don't need no stinking
progressives moderates" and we might have moved on to "You're eating veal! It's veeal! It's made from veeeeeeaaalll!!!!".
...or that going extreme is not the best choice for an election...
Bernie's not extreme. He's the only actual centrist. Without him, we'll get a contest between two right-wingers arguing over which feather on that wing is better. But one of his failings as a campaigner has been not framing it that way enough. (And going too easy on fellow Democrats in general.)
But again, the thing about there not being enough voters is kind of built in to the premise of a loss in the first place; it's true no matter who loses or what kind of campaign they lost with. Are you trying to get at the issue of
why more people don't vote our way? Again it's a pretty generic idea; one could wonder why more people don't vote
any particular way, so again, I'm not getting why you would expect it to be more noteworthy regarding any one candidate in particular than any other, unless it's because Bernie is much closer to what the people want than Biden or Trump. So the question would really be (and already is, even without your hypothetical scenario) why don't people vote for the candidate whose positions on issues are most like their own. And people have tried to figure that out for a long time. "What's The Matter With Kansas" is 16 years old and even that probably wasn't the first. I imagine that the answer is a complex list of answers weighted differently in different people, including the "ELECTABLE!!!!!" myth, the "socialism" myth(s), miseducation or noneducation on what different political & economic systems & theories & their results are in general, mainstream media corporations' hostility to non-corporatists, unawareness of which politician stands for what on which issues, internal machinations within a party, election manipulation both within primaries and in general elections, the huge financial advantages wielded by corporations thanks to our system of legal bribery and private funding of election campaigns, and more that didn't come to mind while I was typing the sentence.
Short answer: every election has a loss, and those losses are determined by... the same old things that have always determined all other losses.
What is it exactly that people like about Biden other than "he was Obama's VP" and "he's electable"?
Tell me what about him is better than the other 20 candidates that we had because I don't see it other than he is the corporate choice and the corporate media has endorsed him as the candidate to beat trump from before he was even in the race.
His personality/style fits in with the overall mentality that people have gotten so used to from Democrats that it feels like home. Unfortunately, that general overall theme is "weak-willed, befuddled, beaten-down; loser", but still, it's so intertwined with the definition of "Democrat" lately that a Democrat who isn't constantly looking for the next opportunity to capitulate just in case they might lose again is an alien concept to try to wrap one's mind around.
