Prof. Spence who writes at Vision Circle (yeah, that's still Lester but when you know a person has earned his title you oughta give it up once in a while) has an article titled Race, Religion and the DNC at Africana.com. Good stuff…he considers two possible reasons the DNC hasn't gotten religion from Black folks, and why they should.
He also presents a third option, but that's the DLC position.
