AP: “The partisan political divide over the potential nomination of U.N. Ambassador Susan Rice to be secretary of state intensified Sunday with Republicans questioning her fitness for the job and Democrats defending her.”
“President Barack Obama could name his next defense secretary in December, far sooner than expected and perhaps in a high-powered package announcement with his choice for secretary of state, several senior administration officials tell The Associated Press. The personnel moves, coupled with Obama’s coming choice for a new leader of the Central Intelligence Agency, will be viewed by U.S. allies and enemies alike as signal of how he will pursue national security in a second term.”
More: “The top names under consideration for defense secretary are former Republican Sen. Chuck Hagel of Nebraska, former top Pentagon official Michele Flournoy, Deputy Defense Secretary Ashton Carter and Democratic Sen. John Kerry of Massachusetts.”


Why not John McCain for defense secretary?
Because he's a lunatic.
I dont think he is a lunatic, and as he served in the armed forces, he may be a good selection, as would John Kerry
I think Kerry would also make a good choice for Sec. of State when Hillary leaves.
If I were President Obama, I would even ask Colin Powell if he had any interest in Sec of Defense.
Whether McCain is or is not a lunatic, he would definitely be a loose cannon as Secretary of Defense. No president would want him in that role.
Tommy, down in #4. I agree with your picks.
Give Susan Rice Sec. of State and Chuck Hagel Sec. of Defense. Colin Powell as CIA Director. This would be a great Cabinet!! Independent voters would love these picks!!
I dont know about Susan Rice as I dont know much about her except for the recent Benghazi stuff, so I wont comment either way on her.
If not her, then John Kerry as I said earlier. The other two that you mention would be good in my opinion.
John "bomb, bomb, bomb......bomb, bomb Iran" McCain has as much chance of being nominated (by POTUS) for Sec. of Defense as Mitch McConnell had to be nominated as his campaign manager.
It's safe to say McCain (& possibly Graham) have no more bridges left to burn.
Barney Frank for Sec. of Treasury.
