This is not extraordinary. It would be quite natural for Democratic candidate Barack Obama to move from his mainline, UCC background to a "born-again" African American environment. Why? First, because there are more social-justice affinities than differences between mainline denominations and the bulk of African American churches, even "born-again" ones. Second, Obama has an IAF background. The Industrial Areas Foundation has made a habit of building coalitions for decades between mainline and African American churches by focusing on their common interests.
Believe me. I'm not talking out-of-school. Or basing this strictly on my own opinion.
