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.
Here's a look at the major Obama players and some candidates to fill any openings based on ABC News reporting, beltway buzz and outside reports.
Clinton has openly and unambiguously pledged to step down from her post in a second Obama term, though she told State Department employees in January that she "will certainly stay on until the president nominates someone and that transition can occur."
Secretary of State is "my last public position," Clinton said in a December 2010 interview. "I will probably go back to advocacy work, particularly on women and children and probably around the world."

Geither, the longest-serving member of Obama's economic team, said earlier this year that he would not return to the administration in a second term. "I'm confident he'll be president," he told Bloomberg News, speaking of Obama. "But I'm also confident he's going to have the privilege of having another secretary of the Treasury."
During an appearance on ABC's "This Week" in April, Geithner said the next Treasury Secretary would need to be someone who is "willing to tell [Obama] the truth and, you know, help him do the tough things you need to do."

When asked if he'll stay for a second Obama term, Holder told a Senate Judiciary Committee hearing earlier this year: "What my future holds, frankly, I'm just not sure." Holder, the first African-American U.S. attorney general, is said to want to remain in the job but recognizes that controversies have marked his tenure. "Some have raised concerns about whether I was tough enough. I hope people will see ... [that I] stuck by my guns," he said. "I've lost some, I've won more than I've lost."

But I left a lot of my stuff in Arizona, and I'm still a registered voter there."

Sebelius is expected to remain in her post well into a second Obama term to oversee further implementation of the administration's health care law. "So much of what we're working on isn't fully enacted until 2014," she told the Kansas City Star in September. "I can't imagine walking out the door in the middle of that?. I could say to him, 'Good luck, hope that goes well.' I don't think that works really well."
Donovan has said it's ultimately up to the president but that he would like to remain the head of the agency responsible for promoting home ownership, affordable rental residences and community development. "I've loved serving him. But ultimately he's going to decide who his team is," he told CSPAN in October. "I've loved what I'm doing. I think we're making a real difference in families' lives. I'm very, very happy with the work that I'm doing."
