After Barack Obama picked Joe Biden as his running mate, the GOP launched the Biden Gaffe Clock. It's still in its infancy, but if you click here, you can catch some wince-inducing footage of Biden calling Obama--wait for it--"Barack America." (The look on Obama's face is just priceless.)
A question: might the Biden pick bode poorly for Mitt Romney? After all, Mitt's something of a gaffe-meister himself--and if he's tapped as McCain's VP, the Republicans might have to abandon this line of attack.
