Hello, Chicago. If there is anyone out there who still doubts that America is a place where all things are possible, who still wonders if the dream of our founders is alive in our time, who still questions the power of our democracy ,tonight is your answer. ...... I was never the likeliest candidate for this office. We didn't start with much money or many endorsements. Our campaign was not hatched in the halls of Washington. It began in the backyards of Des Moines and the living rooms of Concord and the front porches of Charleston. It was built by working men and women who dug into what little savings they had to give $ 5 and $ 10 and $ 20 to the cause. It grew strength from the young people who rejected the myth of their generation's apathy , who left their homes and their families for jobs that offered little pay and less sleep. It drew strength from the not-so-young people who braved the bitter cold and scorching heat to knock on doors of perfect strangers, and from the millions of Americans who volunteered and organized and proved that more than two centuries later a government of the people, by the people, and for the people has not perished from the Earth. This is your victory. And 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. ...... 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. I promise you, we as a people will get there. The purpose of the speaker is to do the following except  _  .
expressing thanks to his supporters discussing the challenges that lie ahead urging Americans to unite for the bright future of the nation warning the people against two terrible wars in store
