Two new polls with very different results show that the black vote in South Carolina is not homogeneous, and no candidate has completely locked up this bloc in the state.
A Winthrop University poll of African-Americans in the state show that U.S. Sen. Barack Obama, D-Ill., had an almost five-point lead over U.S. Sen. Hillary Clinton, D-N.Y., and no other Democratic candidate had more than 3 percent.
