Happy birthday, Mr. President.
Obama turns 51 on Saturday, when he'll celebrate in Chicago with a backyard party. Two supporters will be conveying their birthday wishes face to face, after the Obama campaign offered invitations to the president's party as an incentive to make a political donation.
Barack Obama was born Aug. 4, 1961 at Kapiʻolani Maternity & Gynecological Hospital in Honolulu, Hawaii.
