It is great to be back in Denver. I was here last summer -- we had a good time to accept the nomination of my party and to make a promise to people of all parties that I would do all that I could to give every American the chance to make of their lives what they will; to see their children climb higher than they did. And I'm back today to say that we have begun the difficult work of keeping that promise. We have begun the essential work of keeping the American Dream alive in our time. And that's why we're here today.
