When we don't pay close attention to the decisions made by our leaders, when we fail to educate ourselves about the major issues of the day, when we choose not to make our voices and opinions heard, that's when democracy breaks down. That's when power is abused. That's when the most extreme voices in our society fill the void that we leave. That's when powerful interests and their lobbyists are most able to buy access and influence in the corridors of power - because none of us are there to speak up and stop them.

That's why I stand here tonight. Because for two hundred and thirty two years, at each moment when that promise was in jeopardy, ordinary men and women - students and soldiers, farmers and teachers, nurses and janitors - found the courage to keep it alive.

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

Our country was born out of a desire to be free. And every day since, it's been protected by our men and women in uniform - people who believed so deeply in America, they were willing to give their lives for it.

And to all those who have wondered if Americas beacon still burns as bright - tonight we proved once more that the true strength of our nation comes not from our the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity, and unyielding hope. For that is the true genius of America - that America can change. Our union can be perfected. And what we have already achieved gives us hope for what we can and must achieve tomorrow.

Libya is still a mess right now.

Rather, my perceptions about how we solve problems in health care or education span across a whole range of areas. And I want to try to capture that complexity.
