When we helped prevent the massacre of civilians trapped on a distant mountain, here's what one of them said: "We owe our American friends our lives. Our children will always remember that there was someone who felt our struggle and made a long journey to protect innocent people." That is the difference we make in the world.

Letting the free market do whatever it wants. That's not been historically how we grow. We have to invest in education, in rebuilding broadband lines and roads and runways, and it's important that we bring back American manufacturing and regulations to prevent consumers from being cheated.

We can give our intelligence and law enforcement community the powers they need to track down and take out terrorists without undermining our commitment to the rule of law, or our basic rights and liberties.

I know there are problems that I say to myself, If maybe I was a little more gifted I might have been able to solve. But that's not because I believe what I did was a mistake. It's that maybe it required the talents of a Lincoln.

I would put our legislative and foreign policy accomplishments in our first two years against any president - with the possible exceptions of Johnson, FDR, and Lincoln - just in terms of what we've gotten done in modern history. But, you know, but when it comes to the economy, we've got a lot more work to do. And we're gonna keep on at it.

Now we're in the midst of not just advocating for change, not just calling for change - we're doing the grinding, sometimes frustrating work of delivering change - inch by inch, day by day.

If you run you stand a chance of losing, but if you don't run you've already lost.
