Elections have been decided, and will be decided for the foreseeable future, by people we've never met before and will never meet.
People like Contra/Vaush/etc. really just seem like they have Bernie Syndrome and desperately don't want libs to blame them if Biden loses, despite the fact that they'll do that literally no matter what because libs are largely incapable of self-reflection.
It doesn't even matter who you vote for. Biden isn't going to fundamentally change anything and he isn't going to be that much worse than Trump if at all.
His foreign policy is probably going to be massively worse.
