After months of flirting with a presidential candidacy, and a week of heavy petting, former New York governor George Pataki has decided not to run after all. According to YNN, a “source insisted that Pataki’s decision was based mainly on family concerns.” Presumably, the family was concerned that a concussion or some other kind of brain trauma had convinced Pataki that his doomed campaign would be anything but a late-night punch line. With Pataki now out, the contours of the race … remain completely unchanged.
