We know a history so that we can learn from it. We learn our history because we understand the sacrifices that were made before, so that when we make sacrifices we understand we're doing it on behalf of future generations.

If they bring a knife to the fight, we bring a gun.

We, the people, still believe that every citizen deserves a basic measure of security and dignity. We must make the hard choices to reduce the cost of health care and the size of our deficit. But we reject the belief that America must choose between caring for the generation that built this country and investing in the generation that will build its future. For we remember the lessons of our past, when twilight years were spent in poverty and parents of a child with a disability had nowhere to turn.
