The polls in South Carolina closed at 7 pm. By about 7:01 pm, news outlets felt comfortable calling the race.
Barack Obama routed Hillary Rodham Clinton in the racially-charged South Carolina primary Saturday night, regaining campaign momentum in the prelude to a Feb. 5 coast-to-coast competition for more than 1,600 Democratic National Convention delegates.
Former Sen. John Edwards of North Carolina was running third, a sharp setback in the state where he was born and scored a primary victory in his first presidential campaign four years ago.
The Associated Press made its call based on surveys of voters as they left the polls.
About half the voters were black, according to polling place interviews, and four out of five of them supported Obama. Black women turned out in particularly large numbers. Clinton and Edwards each won roughly 40 percent of the white vote, with about 25 percent going to Obama, the first-term Illinois senator.
More soon.
