"I don't in any way underestimate the difficulties, because it's only gotten harder. But I do think you just have to go into politics with the attitude that you're going to speak clearly and authentically about what you see the country needs...and seek out whatever possible partners you can, even in the other party. I've looked at successful presidents going back. Some of our most successful governed through periods when their party was in charge, and when the other party was in charge. There's no magic formula."
