"We do not respect your son. We do not respect what he's doing all over the world," a woman audience member bluntly told Bush after his keynote speech.

The retired president had just finished a folksy address on leadership by telling the audience how deeply hurt he feels when his son the president is criticized.
"This son is not going to back away," Bush said, his voice quivering. "He's not going to change his view because some poll says this or some poll says that, or some heartfelt comments from the lady who feels deeply in her heart about something. You can't be president of the United States and conduct yourself if you're going to cut and run. This is going to work out in Iraq. I understand the anxiety. It's not easy."
