It's worth noting that even if true, this sounds like a standard robbery with an insane, politically-related act tacked on after the assailant noticed a McCain bumper sticker. Even in the victim's telling, the original assault was not about politics.
Reasonable caveats from Ed Morrissey (who is also a little dubious):
Not too many young women would scar their faces just to create a political hoax. As for the reversed/upside-down B.... [i]t could have gotten reversed on the computer, or the attacker may have had her on the ground with her head upside-down in relation to his.
Clearly something terrible happened here, but I'd be happy to say nothing about it because it has no real relevance to the campaign--except that it's clear some people, notably Drudge, are determined to make it an issue in a critical swing state where race is probably a factor. (Yes, her attacker was allegedly African-American, which I assume is supposed to give it special resonance in certain quarters that John Murtha can tell you about.)
