Lisa Schiffren over on NRO gets at why the choice of Biden might be a pick Senator Obama wishes he didn't make:
"Joe Biden embodies so much of what Obama claims to want to change — in particular, a Washington of time servers in love with process, casual about morality, and acutely aware of self-interest. Biden is no intellectual. He's smart enough for a U.S. senator. But he brings no depth to the ticket. As others have mentioned, he brings Washington experience, which is different than real experience. He has never run anything or made anything happen. He is not presidential material..."
Don't you get the feeling that, once the newness of the Biden pick wears off, many Americans will find him to be a real snoozer who adds nothing? I do.
