Bob McDonnell, left, as he arrives for a rally in Richmond, Va. McDonnell is preparing to leave office after a four-year term that saw his rising national profile fade under the cloud of a federal investigation. McDonnell, once mentioned as a possible vice presidential pick, is leaving in January because of term limits. He told The Associated Press in an interview that he has no plans to seek another office but that he expects to remain engage in policies he cares about. (AP Photo/Steve Helber, File)
