Look who's in charge, VP Biden. No offense to him personally but politically and historically speaking the position of VP has been about one of the most useless positions imaginable. I believe he's in charge so the Dems can appear to be "on the job" on an issue they are hoping is going to quietly (more or less) go away so they don't have to stick their necks out too far.
That's a very good point. I wouldn't ask Biden to handle something I was dead set on winning.
