ABC news is predicting that Obama won the 2012 election with 275 electoral votes over former Massachusetts Governor Mitt Romney.
The candidate must receive 270 electoral votes to win.
In the days before the election, polls showed a tight race, with 50 percent support for Obama and 47 percent for Romney in a ABC News/Washington Post tracking poll.
However in Missouri, Romney led the US Survey poll with 7-points over Obama.
Obama served three terms representing the 13th District in the Illinois Senate from 1997 to 2004, running unsuccessfully for the United States House of Representatives in 2000.
He won the Illinois U.S. Senate election in November 2004, serving until his resignation following his 2008 presidential election victory.
His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination.
In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009.
Nine months later, Obama was named the 2009 Nobel Peace Prize laureate.
In April 2011, he announced that he would be running for re-election in 2012.
Obama is the 44th President of the United States. His Vice President is Joe Biden.
