Coming from Biden's eyes; He may be too stupid to realize he's the sacraficial lamb. But he's going to have to start playing his part or there will be phone calls. You'll know when he starts talking about Beau and how his only remaining son was such a good kid etc. His job at that point will be to bleed out and blame Trump.
Joe mentioned beau today. He’s teaching at a west coast law school so not sure when he will join him on campaign trail.
