Michael Whatley, the chairman of the North Carolina Republican Party, explains why state GOP leaders brought the case to the nation’s highest court. Bob Phillips of Common Cause North Carolina breaks down why his group opposes the GOP’s efforts, and what he thinks the outcome could mean for elections across the country.
