In what has been widely rumored for months, CIA Director Leon Panetta will replace Secretary of Defense Robert Gates and General David Petraues will replace Panetta at the CIA.
This effectively takes out of the running the potentially greatest threat to President Obama's 2012 election chances with Petraeus at CIA. Petraeus has long been a dream candidate for the GOP with his stellar military and foreign policy chops, not to mention excellent communication skills. Panetta's long experience in government and relatively tranquil service at the CIA would seem to have helped him move to the Pentagon.
As another sweetener, Ryan Crocker has been appointed as special envoy to Afghanistan. Crocker was Petraeus diplomatic partner in Iraq during the successful surge.
