While President Obama prepares to tackle the looming fiscal showdown with Congress and fine tune his policy objectives for his second term, he must also prepare to retool his Cabinet and his core White House team.

The Obama administration has had one of the lowest Cabinet turnover rates in history. But as with most second-term presidents, a number of Cabinet-level officials and those with Cabinet rank, have already announced or indicated their intent to leave as President Obama begins his second term.

Among them are Treasury Secretary Tim Geithner, who has announced his intent to leave and Secretary of State Hillary Clinton, who until recently, was also on record as having decided to serve only one term.

Meanwhile, the departures of Attorney General Eric Holder, Energy Secretary Steven Chu, and EPA Administrator Lisa Jackson are now seen as increasingly likely. Rumors are also circulating that Jack Lew will also resign his post as White House Chief of Staff for the President’s second term, according to senior analysts at Wexler & Walker Public Policy Associates, a public policy and lobbying firm has been following the revolving doors of Washington since 1981.

Add to that Federal Reserve Chairman Ben Bernanke’s recent announcement that he will not stay on when his current term ends in 2014, along with likely changes within the Office of Management and Budget, and its easy to see that President Obama and his advisors will have their hands full lining up suitable replacements that will pass muster with Congress.

While the circumstances unfolding around the unexpected resignation of CIA Director Gen. David Petraeus has drawn attention away from the expected executive shuffle in the White House, Wexler & Walker have assembled a list some of the most likely candidates to keep an eye on.
