DC, neither of the candidates is President yet. Thus, neither has the necessary exposure to military commanders and the Joint Chiefs or the level of information on which to base an Iraq exit strategy. Obama has stated that he anticipates withdrawal within 16 months. That's all he can realistically state.

Also, I reiterate, it is important for him to refer to the way we got into Iraq because McCain exercised bad judgement in backing the invasion. Thus, it is important for Obama to emphasize that distinction between he and McCain and McCain's judgement. Besides, not all Americans support our withdrawal from Iraq.
