I hate to make light of a person with an obviously troubled pyschology, but it just struck me that the image of Ashley Todd, the young McCain volunteer who made up the story of her mugging, is the perfect image for the McCain campaign itself:

Battered and bruised by a bunch of self-inflicted wounds, and literally branded with a 'B', symbolizing how McCain just got owned by the better candidate.  All of McCain's negative ads and wacko attacks have boomeranged and given him a huge black eye, and he has only himself to thank.  Now, his onetime supporters and promoters have suddenly fled in the face of his perfidy, leaving him bewildered, lost in the headlights of the on-coming train.
