I'm really worried that the Democratic leadership is shooting itself in the foot.

A significant portion of the voter base that the Democratic party is counting on has serious and legitimate problems with the policy decisions of the administration. They're making their thoughts known through all the channels they should theoretically be using; peaceful protest, petitions, letters etc.

Rather than addressing and validating any of these concerns the overwhelming response has been to ridicule those voters. People don't respond well to, "Fuck you. Do what you're told." but that's all they're getting. Whenever people point this out the typical response is more of the same. All variations of, "It doesn't really matter what you think or what you expect your elected official to do. Just shut up and vote for Biden."
