A follow-up on expectations ... From the same Politico article:

But if Palin will be under an intense spotlight thanks to doubts about her basic competency, Biden's challenge will be to not prove just how much he knows.

Seriously? Joe Biden is supposed to avoid showing that he has knowledge? Because apparently if there's anything you don't want in the person who is a heartbeat away from the presidency, it's ... knowledge.

Has there ever been a dumber standard set for a debate participant?
