You did it because you understand the enormity of the task that lies ahead. For even as we celebrate tonight, we know the challenges that tomorrow will bring are the greatest of our lifetime -- two wars, a planet in peril, the worst financial crisis in a century.
Even as we stand here tonight, we know there are brave Americans waking up in the deserts of Iraq and the mountains of Afghanistan to risk their lives for us.
There are mothers and fathers who will lie awake after the children fall asleep and wonder how they'll make the mortgage or pay their doctors' bills or save enough for their child's college education.
There's new energy to harness, new jobs to be created, new schools to build, and threats to meet, alliances to repair.
The road ahead will be long. Our climb will be steep. We may not get there in one year or even in one term. But, America, I have never been more hopeful than I am tonight that we will get there.
