Michael Seppanen, I understand your disappointment in Democratic Nominee to be. Joe Biden is not especially talented, too old and should have been discouraged from running in the first place. Read my article "Let's Get Real -- Joe Bden is Not up to the Job" on MEDIUM.
That said, we have what we have, and the alternative of continuing with Donald is unexceptable.
The VP choice is important because the person is positioned for the Presidency or to block it from another more talented. Susan Rice would fit the bill as you don't need campaigne razz-ma-tazz this time around.
I thought it a goof for Biden to limit his choices "Joe's Running Mate Needs to have Red Hair" on MEDIUM.
