What is the best way for Joe Biden to answer the followind debate question:

[onenote]

It wouldn't come as a shock (although I'm not predicting it will happen) for the following question directed towards Joe Biden during the debate: "Sen. Biden, do you think Gov. Palin is qualified to be vice president?"

While the ultimate answer to the question is obvious, the more difficult issue is how Biden frames his response so that he doesn't come across as arrogant or "beeating up the girl".

Anyone have thoughts (serious ones) as to how Biden might best respond?
