iLesson is a series of Obama life lessons
Several events brought Obama to national attention during his campaign to represent the State of Illinois in the United States Senate in 2004, including his victory in the March 2004 Illinois Democratic primary and his keynote address at the Democratic National Convention in July 2004. He won the 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.
