My impression of Clinton is that she examines every political issue against the light of her career. While there is nothing particularly wrong with that, I believe that would preclude a cabinet position.

I think a Secretary of State should have foregone a political life of their own, at least for the duration, be able to support a President's policies and to be able to act in the interest of the President and the US in dealing with foreign policy issues.

That the Secretary of State would be an advisor to the President, and not the other way around. And it would be best if the Secretary of State were not busily positioning herself to run against the incumbent President for the job in 2012.

I don't think Hillary would ever accept.
