He's been totally and thoroughly humiliated.
Humiliated by Trump at the debates and now humiliated by his own party, by the people he's called his closest friends.
This is why he's hiding out in Delaware. He just can't bear to show his face in DC for a while.
I think that is a very good comment. In addition to just being humiliated, it is the first time its happened to him in his political career. I think they broke his spirits.
I still have no sympathy for the venal old SOB.
