Obama campaign senior adviser said on Fox News Sunday that the president leads Mitt Romney -- albeit slighly -- in the battleground states, but expects a close contest on Election Day.
"I think that we have a lead in this race, it's a slight lead. It's going to be a close race," he said. "We expected a close race. We're going to have a close race. And we're doing everything that we can to make our case to the American people, and Charlotte's going to be a big part of that."
