"Get back to me when Congress declares War on Iraq."
Congress did give the President authority shortly after 9/11.
Some would call it consitutional over-reach. Like the Gulf of Tonkin Resolution. I haven't heard anyone refer to it as the Police Action in Iraq.
Point being, if you attack one over-reach, if you're sincere, you need to attack them all. Otherwise, don't use the soldiers as fodder for your argument.
