I've chosen to be a commentator and an analyzer of politics, rather than an actual doer of it. I think it could have gone the other way, but I'm not sorry that it didn't, because this made it easier to be home with my kids and to spend time with them. Writing you can do right in your house. You don't have to go anywhere.

Lincoln had internalized the pain of those around him-the wounded soldiers, the captured prisoners, the defeated Southerners. Little wonder that he was overwhelmed at times by a profound sadness that even his own resilient temperament could not dispel.

I think after Sandy Hook, when Obama went out, and he talked a lot about gun control and met with the parents, there was a sense that something was going to happen. But then, I guess, the power of special interests was greater than public sentiment.

If you interview five people about the same incident, and you see five different points of view, it makes you know what makes history so complicated. Something doesn't just occur. It's not like a scientific event. It's a human event. So the dimensions of it will be seen differently by different people.

It took me five years on Lyndon Johnson, ten years on the Kennedys, six years on the Roosevelts. Inevitably, you get shaped by the people that you're thinking about during that period of time.

Good leadership requires you to surround yourself with people of diverse perspectives who can disagree with you without fear of retaliation.
