That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.

Hope is the bedrock of this nation. The belief that our destiny will not be written for us, but by us, by all those men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.

I always say that campaigning and governing are two different things.

We don't quit. I don't quit. Let's seize this moment.

I absolutely think that it's possible for us to find common ground.

[Our troops in Iraq and Afganistan] does give us the ability to make sure that we are strengthening those folk who are interested in building up their countries rather than destroying them, and doing so in a way that is sustainable and doesn't put a constant burden on the amazing men and women that we've got in uniform.

For the young people here: practicality is a good thing. There are times where compromise is necessary. That's part of wisdom. But it's also important to hang on to what you believe.
