Several high-level departures are expected both at the top of key Cabinet agencies and within the West Wing. Secretary of State Hillary Rodham Clinton and Treasury Secretary Timothy Geithner, below center, made clear their intentions to leave sometime after the election.
Secretary of State: Possible successors include U.N. Ambassador Susan Rice, Sen. John Kerry, D-Mass., national security adviser Thomas Donilon.
Treasury Secretary: Possible successors are White House Chief of Staff Jacob Lew, or Erskine Bowles, the former chief of staff to President Bill Clinton.
Secretary of Defense: Leon Panetta, at far right, is expected to retire to his California walnut farm, although he may stay in his post until the confrontation with Congress over the impending expiration of the Bush-era tax rates and the scheduled automatic budget cuts is resolved. One Democratic contender to replace Panetta is Deputy Defense Secretary Ashton Carter.
