"Sen. Barack Obama, vying to become the nation's first black president, has won the South Carolina primary today, ABC News projects, boosted by record turnout of African-American voters in a state whose electorate appears polarized along racial lines.


While the race for second-place is too close to call, Sen. Hillary Clinton appears to be leading former Sen. John Edwards in the race for second. This is the second win of the nomination battle for Obama, who won the Iowa caucuses earlier this month, but this is his first win in a state with a sizable African-American population."
