The African-American turnout is 35 percent: The big question among pollsters this week is how many blacks will vote in North Carolina.
In 2004, 32 percent of N.C. voters were black. In early voting this year, the total was just more than 40 percent. The latter total is likely due to Obama's significant get-out-the-vote efforts, but if Obama can approach that number today - say, a 35 percent black turnout - his win will be more than five points. If the turnout is less than 30 percent, Clinton will be celebrating.
