I recognize the Biden type from my experience in the working world. A man who is deeply flawed and problematic is brought along by the powers that be BECAUSE he is no danger to them. He’ll always support them, no matter what, because they put the butter on his bread, and they supply the bread. The real problems arise when the powers that be move on. Who is the logical choice to succeed them? Well, the deeply flawed and probably incompetent person they were using to guard their back. This person is invariably unable to fill the shoes he suddenly finds himself clomping around in.
If he was on Star Trek, he’d be wearing a Red Shirt................
