“I have strengths and I have weaknesses, like every President, like every person,” Obama told me. “I do think one of my strengths is temperament. I am comfortable with complexity, and I think I’m pretty good at keeping my moral compass while recognizing that I am a product of original sin. And every morning and every night I’m taking measure of my actions against the options and possibilities available to me, understanding that there are going to be mistakes that I make and my team makes and that America makes; understanding that there are going to be limits to the good we can do and the bad that we can prevent, and that there’s going to be tragedy out there and, by occupying this office, I am part of that tragedy occasionally, but that, if I am doing my very best and basing my decisions on the core values and ideals that I was brought up with and that I think are pretty consistent with those of most Americans, that, at the end of the day, things will be better rather than worse.”
