When does life start? When does it end? Who makes these decisions?... Every day, in hospitals and homes and hospices... people are struggling with those profound issues.

Making college affordable is a really important goal, and my plan will work better than Senator [Bernie] Sanders' plan by everybody who has looked at it.

I think I've been very consistent in my values.

Donald was one of the people who rooted for the housing crisis. He said, back in 2006, gee, I hope it does collapse because then I can go in and buy some and make some money. Well, it did collapse.

Every presidential candidate for decades has released his tax returns, and I've released 33 years of my tax returns. The American people deserve to know about our taxes. And so Donald Trump is standing in the way of precedent that goes back on both sides of aisle Democrats and Republicans, and he clearly has something that he doesn't want us to see.

A lot of the people in history who I really admire lived before the hyperinformation age we're living in. Even if they were governing or solving problems in consequential periods, like the Civil War or the world wars or the Great Depression or the Cold War, they had a period of time and space to actually think, to be private and you read their biographies, and they had time to think about what was happening and how to respond. I don't think human nature has changed in the last 50-150 years, but the stresses, the demands on those of us in public life have just exploded.

I also learned that a person was not necessarily bad just because you did not agree with him, and that if you believed in something, you had better be prepared to defend it.
