Remember this - I never suggested that change would be easy, or that I can do it alone. Democracy in a nation of three hundred million people can be noisy and messy and complicated. And when you try to do big things and make big changes, it stirs passions and controversy. That's just how it is.
Those of us in public office can respond to this reality by playing it safe and avoid telling hard truths. We can do what's necessary to keep our poll numbers high, and get through the next election instead of doing what's best for the next generation.
But I also know this: if people had made that decision fifty years ago or one hundred years ago or two hundred years ago, we wouldn't be here tonight. The only reason we are is because generations of Americans were unafraid to do what was hard; to do what was needed even when success was uncertain; to do what it took to keep the dream of this nation alive for their children and grandchildren.
