I know you didn't do this just to win an election and I know you didn't do it for me. 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 is new energy to harness, new jobs to be created, new schools to build, and threats to meet, alliances to repair.
