Nov. 7, 2012 -- intro: President Obama's victory Tuesday means he will pivot almost immediately to shoring up the team of top aides and cabinet secretaries who will help him tackle the looming fiscal cliff negotiations with Republicans and the full legislative agenda to follow.

While the president's White House staffers have undergone some serious changes during his first term, his cabinet secretaries have remained remarkably stable. That is sure to change. Several high-profile members are expected to step down from their roles in early 2013.
