     Obama will take office and become the 44^th president of the USA on January 20,2009. He is the first African-American in American history to be president. At the same time he is one of the youngest presidents.He is so determined that before announcing his presidential candidacy, he began a well-publicized effort to quit smoking.

    Obama described his election as “a defining moment” in the historyof the United States,saying that “change has come to America.” However, when he does become president, he will face many serious challenges, including two  foreign wars, climate change and what he has describedas “the worst financial crisis in a century.”
