"We treat presidential speeches as if they are written by speechwriters, then handed to the President for delivery. If I could show you one experience from my time working for President Bush, it would be an editing session in the Oval with him and his speechwriters. You think that me cold-calling you is nerve-wracking? Try defending a sentence you inserted into a draft speech, with President Bush pouncing on the slightest weakness in your argument or your word choice. In addition to his analytical speed, what most impressed me were his memory and his substantive breadth. We would sometimes have to brief him on an issue that we had last discussed with him weeks or even months before. He would remember small facts and arguments from the prior briefing and get impatient with us when we were rehashing things we had told him long ago. And while my job involved juggling a lot of balls, I only had to worry about economic issues. In addition to all of those, at any given point in time he was making enormous decisions on Iraq and Afghanistan, on hunting al-Qaeda and keeping America safe. He was making choices not just on taxes and spending and trade and energy and climate and health care and agriculture and Social Security and Medicare, but also on education and immigration, on crime and justice issues, on environmental policy and social policy and politics. Being able to handle such substantive breadth and depth, on such huge decisions, in parallel, requires not just enormous strength of character but tremendous intellectual power. President Bush has both."
