Bill Clinton, America's 42nd president, says he's ready to stay out of his wife's way as she serves as president 44's secretary of state. Bill told CNN that he would act as Hillary's sounding board, but doesn't think he'll do more than that.
As for helping Obama, Bill said he would if Obama asked him "to do something specific." I could imagine Bill acting as America's on-call peace negotiator, dispatched on specialized missions.
Either way it appears that the former president read Cherie Blair's advice to Michelle Obama: learn to like the backseat. Considering Bill's expertise, accomplishments, and ego, it surely will take some effort to keep quiet. Should he?
