Now I know how Mary Mapes felt. Moments (apparently) after the Rather post appeared, here's feedback that includes this reference, to the Hair Part Theory (promulgated, at least in part, to sell a mirror that doesn't mirror--that is, that doesn't reverse left-to-right). If this site is to be believed, Jimmy Carter also toyed with the idea of a changed part. I thought I was being trivial, and still I lumbered into the land of a Theory.
