David Axelrod, a top advisor to President Obama's reelection campaign, said Sunday that he is concerned that Hurricane Sandy could reduce turnout and potentially hurt Obama's campaign.

"Obviously, we want unfettered access to the polls, because we believe that the more people come out, the better we’re going to do," Axelrod said. "And so, to the extent that it makes it harder, that’s a source of concern."

The storm could have a wide-ranging effect on swing states from North Carolina and Virginia to even New Hampshire or Ohio.

Axelrod said that the political implications of the storm remain hard to predict and that the president will be focused on helping the victims.
