I liked her answer. It seemed to me that she was talking about Bush's rush to war in the end of her answer. Or even her own votes before the war. So it could have been an apology.

But in many respects if she was talking about her own decision making process before the Iraq vote frankly it makes her look bad. Because it makes it sound like she had ignored criticism and plans not to let that happen again once she's President.

If so, she made a pretty good argument for people to prefer Barack over her!
