Joe Biden is mad at Barack Obama.
The ad in question showed images of an earlier McCain from the '70s, an old computer, and a disco party. Here was some dialogue of the ad:
"He admits he still doesn't know how to use a computer, can't send an e-mail."
Barack Obama, did you know that John McCain cannot type due to inguries that he received in Vietnam? How disrespectful.
At least Joe Biden is trying to run an honest, respectable campaign.
Ready to lead: No.
Ready to smear: Yes
