As I've said before, at the state level, there are some pretty decent Democrats who recognize whoa, Republicans are out of their fucking minds and should be stopped.
But that doesn't carry over to the national party, where Democrats like Biden will call Mitch McConnell a good friend and insist on the importance of having a strong Republican Party.
Yeah, they don't like Trump, but they're less about defending democracy than they are about preserving the status quo of "normal" politics.
