The world is complicated and full of grays, but there's still truth there to be found.

It's probably a prerequisite for the job, or at least you have to have enough craziness to think that you can do the job. I think that [Donald Trump] has not spent a lot of time sweating the details of, you know, all the policies.

Civility also requires relearning how to disagree without being disagreeable. Surely you can question my policies without questioning my faith or, for that matter, my citizenship.

My hope is that's something [Donald Trump] is thinking about, because not only is the president of the United States somebody that the entire country looks to for direction but sets the agenda internationally in a lot of ways.

I will sign a universal health-care bill into law by the end of my first term as president that will cover every American and cut the cost of a typical family’s premium by up to $2,500 a year.

The best way to not feel hopeless is to get up and do something. Don’t wait for good things to happen to you. If you go out and make some good things happen, you will fill the world with hope, you will fill yourself with hope.

The Internet and Twitter and all these things are very powerful, but it also means sometimes that instead of having a dialogue we just start calling folks - calling each other names. And that's true on the left or the right.
