McCain Campaign Pushed "Mutilation" Hoax

You know that sad, John McCain worker who hoaxed Pittsburgh, Pennsylvania police (and the rest of us) with a story that a Barack Obama-supporting mugger carved a "B" into her face? Well, it appears that the McCain-Palin campaign pushed this story into the media before getting all of the facts. What is most striking to me, is that McCain is making a Pennsylvania push, trying desperately to flip the state back to red. Is it a coincidence that one of his workers perpetrated this hoax in western Pennsylvania?
