The U.S. Supreme Court issued an 8 to 1 ruling yesterday to exempt a small Texas town from government oversight of their voting process. In a case that could have gutted the key provisions of the historic Voting Rights Act, the law designed to prevent racial discrimination at the polls, the Justices instead issued a very narrow exemption. The Takeaway looks at whether Chief Justice John Roberts is maneuvering in order to build bigger majorities and avoid 5-4 decisions. To help answer that question and to discuss the ruling we turn to Nate Persily, professor of law and political science at Columbia University.
