In an interview that aired on CBS, Sen. Barack Obama’s running mate Sen. Joe Biden, D-Del., distanced himself from an Obama-Biden TV ad.

Katie Couric asked Biden about the “tone of the campaign” adding that “you guys haven’t been completely guilt-free, making fun of John McCain’s inability to use a computer.”

Biden said, in no uncertain terms:

“I thought that was terrible by the way,” Biden said of the ad.

“Why’d you do it then?” asked Couric.

“I didn’t know we did it and if I had anything to do with it, we would have never done it,” Biden said, “and I don’t think Barack, you know, I just think…I don’t think there was anything intentional about that, they were trying to make another point.”

But later, apparently, he was taken to task by Obama and returned with the talking points:

Having now reviewed the ad, it is even more clear to me that, given the disgraceful tenor of Sen. McCain’s ads and their persistent falsehoods, his campaign is in no position to criticize, especially when they continue to distort Barack’s votes on an issue as personal as keeping kids safe from sexual predators.”

You see? An ad needs to be reviewed with the right people around to be understood…..

And human decency has no place in a campaign.
