Senator Biden only needs to answer questions directly to the moderator, kick John McCain and Republcians where needed, and completely ignore the Bimba on stage with him. She is so incoherent she will do her own self in.
But if she is dumb enough to mention Hillary Clinton in lieu of being a woman, Senator Biden should do the first few words of the most famous line in any Vice Presidential debate – when we had a similar setting with Bimbo Dan Quayle.
"I know Senator Clinton, Senator Clinton is a friend of mine…" Smile and leave it at that.
