Obama's running mate...

Alright, so who is this Joe Biden guy anyway?

Wikipedia says he's a liberal, long serving Democrat senator from Delaware.

He has tons of experience--which is what detractors think Obama lacks. And he has a son serving in Iraq, which I guess means something to some people. (Of course it means something, I'm just not sure it means you're a better candidate for it.)

What else do I need to know about this guy?
