President Obama, the nation's 44th president, is seeking a second term in office. The Democrat's rise to power was historic, making him the first African-American president. In 2008, he defeated Democratic Sen. Hillary Clinton's powerful primary campaign and surged ahead of Republican Sen. John McCain in the general election.
Obama graduated from Columbia University in 1983 and later became a community organizer in Chicago. He attended Harvard Law School in 1991 and became the first-African American president of the school's law review. Afterward, he became a lecturer of constitutional law at the University of Chicago Law School.
Obama ran for the Illinois state Senate in 1996 and served from 1997-2004. It was in 2004 that Obama set his sights on Washington, running for and winning Illinois' U.S. Senate seat. He would serve only four years of his six-year term, resigning to run for president in 2007.
A Grammy Award winner, author and Nobel Peace Prize recipient, he is married to Michelle (Robinson) Obama. The couple has two daughters, Malia and Natasha (Sasha).
