This week, North Carolina's governor signed a new law requiring a state-approved photo ID to cast a vote in a polling place and shortening the period for early voting. The move comes just weeks after the U.S. Supreme Court invalidated a key provision of the Voting Rights Act of 1965, which had required large parts of the state to get federal approval before changing voting laws.
Gov. Pat McCrory, a Republican, says the new law will protect the state from voter fraud.
