The latest effort from Team McCain accuses Barack Obama of passing over Hillary Clinton for VP because she spoke the truth about him, and he wasn't too fond of that. Obviously, it's meant to rile up Clinton's supporters, possibly even those at the convention. But it overlooks a couple of things. Biden, the man who wasn't passed over, didn't exactly take it easy on Obama during the primaries. Also, from where I'm sitting here in Denver, I think everyone's too busy registering and getting credentials and such to pay much attention to this ad.
