The Senate voted to confirm General Petraeus Friday.
I've mentioned Petraeus a couple of times recently, but I don't think I've quite crystallized my position. It is reasonable and responsible, as a Senator, to defer to the President on his choice of military commanders. It is also reasonable and responsible, as a Senator, to assume an oversight role over the President's wars. These are fundamentally different views of the same role, but both are defensible.
It is indefensible, however, to attempt to hold both positions simultaneously. If you vote to confirm a commander who says the only way to win in Iraq is by increasing the number of troops, you cannot also vote to condemn an increase in troops.
