For two hours New Jersey Gov. Chris Christie did a full hangout, or at least as close as we're likely to get in politics these days. He held a marathon press conference to respond to the George Washington Bridge traffic scandal that exploded Wednesday and imperiled his presidential aspirations. He announced that he was firing the staffer responsible, cutting some ties with one of his top political aides, and investigating what other abuses might be left uncovered. He then took round after round of questions in which he fulfilled most of the compulsory requirements of the public self-flagellation routine. He apologized, took responsibility, called himself “embarrassed and humiliated,” said the "buck stops here," expressed regret, denounced the activity several times as "callous" and "stupid," and announced that he was visiting the injured parties today.
