Yup. He said it.
And good for him. But make no mistake that from the standpoint of the Obama campaign, Biden just committed a gaffe. And since that whole "I'm Barack Obama and I approved this message" was at the end of the ad and Biden made clear that he most certainly did not approve of the message, the end result is that he has dissed Obama, his boss.
This should make for some enjoyable confusion and apoplexy within the Obama camp--especially if more people in the press do their jobs and ask questions of the campaign concerning this split between the Democratic Party's Presidential candidate and the Democratic Party's Vice Presidential candidate.
