Mike Huckabee and his top advisers insist that he's thinking seriously about running for president, but he's doing little to put together the sort of organization needed to mount a campaign. The latest evidence: Chip Saltsman, his campaign manager in 2008 and one of his closest confidantes, has accepted a job as Chief of Staff for freshman Rep. Chuck Fleischmann (R-Tenn.). In an interview, Saltsman said his taking the job should not be read as an indication about Huckabee's intentions. "I have a Notre Dame clause in my contract," he quipped. "So I can leave if a presidential comes a calling." That's to say that if a once-in-a-lifetime opportunity came along - in football it would be coaching the Fighting Irish, in politics it's running a White House campaign -- he'd be able to take his leave.
