What dangers does Biden face with Palin in the upcoming debate?

My thought on this is that, no matter what his handlers do, Biden cannot resist the urge to smudge Palin for being a woman and a little less versed on some things. He is the human gaffe machine and he will say something stupid. Palin has a quirky personality that can come off as very sarcastic when she is cornered by someone who is trying to screw her. Biden will likely say something ignorant and she will take him to task. He is not going to like debating a woman.
