Campaign encourages Native Americans to register to vote

After a Supreme Court ruling made it difficult for people to register to vote without an address in North Dakota, Stand-N-Vote was launched. The campaign sees Native Americans as a target of voter suppression because many people on reservations don’t have addresses, they use PO Boxes. The campaign is trying to register people to vote with their tribal council. Carol Hills speaks with actor Mark Ruffalo, who is part of the Stand-N-Vote campaign.
