That didn't come across in the hearings a few weeks ago.
I don't know of any blame placed on Petraeus for political decisions at those hearings, as opposed to that directed at the administration.
From the AP story on this:
"Gates said he had consulted with senior lawmakers, including the chairman of the Senate Armed Services Committee, Sen. Carl Levin, D-Mich., about the nominations, and the defense secretary said he anticipated no Capitol Hill obstacles to confirmation."
