The costly and bitter race was also a close one.
The returns from 79 percent of the nation's precincts put Obama with 52.2 million votes at 49.5 percent. Romney had 51.7 million, 49 percent.
Obama won in the battleground states of Ohio, Wisconsin, Iowa, Virginia, New Hampshire, Colorado and Nevada.
Romney won North Carolina. Florida was too close to call, and Obama led with a narrow margin in a state where there were still long lines of voters at some polling places after the designated closing time.
Locally, Baton Rouge incumbent Kip Holden (Democrat) defeated challenger Councilman Mike Walker (Republican), Gordon Mese (No party) and "Steve" Myers (No party) in a landslide for the position of Mayor-President of the City of Baton Rouge.
This will be Holden's third term as Mayor-President.
Holden garnered most of the votes at 60 percent with Walker winning 34 percent, according to unofficial results from the Secretary of State's website.
Mese, who runs Garden District Nursery, finished in third place with 3 percent, and Myers, a lawyer and property manager, won 2 percent of the votes.
Holden, a Democrat, became the parish’s first black mayor-president when he defeated incumbent Bobby Simpson in 2004 with 54 percent of the vote.
