Per the insiders: Obama's top contender for secretary of defense is ex-Clinton naval secretary Richard Danzig, with ex-Georgian senator Sam Nunn also in the running. Robert Gates wants to stay in place but his chances are slim.
Long time Obama advisor, Susan Rice, is in pole position for the national security advisor with ex-Clinton NSA Tony Lake, a mentor to Obama, an outside bet.
For secretary of state, Biden had been a lock, but with the vice presidential choice, GOP senator Dick Lugar is a distinct possibility. However don't expect Dick Holbrooke or Jamie Rubin to get much - Lake vetoes Holbrooke and Rubin was far too anti-Obama during the primary.
