South Carolina’s Democratic primary isn’t for a week, so it’s getting less attention. But the stage is set for a pretty big Obama victory.

Emory University professor Merle Black, speaking on POTUS08, says that the Obama will clean up the African-American vote while the white vote will split three ways, between Hillary, Obama, and Edwards. (African-Americans made up almost half of Democratic primary voters in the state in 2004.) He’s skeptical of the argument that African-American women will break for Hillary, as this demographic broke heavily for “Uncommitted” — and presumably preferred Obama — in Michigan.

Black also notes that Huckabee should get “a plurality” of evangelicals in South Carolina and have “a good night.”
