I'd imagine that Biden will be as cool and statesman-like as possible. The woman is simply way too far out of her league. Biden knows he needs to do very little to show she is unqaulified. She'll dig her own grave. I imagine Biden will bring up a few of the more controversial issue regarding Palin if she goes uncharacteristically on the attack.
It should be a massacre.
