If Biden can’t win in a landslide, it’s because Joe Biden sucks, not because the youth are entitled, bourgeois, ignorant, lazy, or any of the other insults being thrown around in this comment thread.
I don’t think “kids these days” are entitled, lazy or ignorant but to a degree both these types of things can be true. Biden is unappealing, yes, but everywhere I turn are people arguing that both parties are the same and that Democrats have done nothing for them. In these cases, when pressed it turns out they just don’t actually know one way or the other. It’s a generalized sentiment of “politicians bad” and many are surprised to learn of even a handful of things Dems and Biden have done that they support.
So I guess you could argue that Democrats suck at marketing. But I’d also argue that many of us suck at understanding politics.
