Barack Obama's expected to produce a record turnout of African American voters in California, and that could have an impact beyond the presidential election. Also on the state ballot is Proposition 8, which would overturn the State Supreme Court's ruling that same-sex marriage is a constitutional right. Prop 8 supporters say Obama's big turn-out will favor a yes vote, because blacks are opposed to same-sex marriage. But they're also supporters of civil rights. Obama himself is opposed to same sex marriage, but he's also against Prop 8, which he calls divisive and discriminatory. We hear several voices on what's being called the "Obama Effect."
