The presidential election is just six weeks away, and one of the big questions on the horizon is who will be eligible to vote?
Today, a federal panel in Washington D.C. is scheduled to hear closing arguments from the state of South Carolina regarding voting rights.
A new law there requires voters to show photo ID and critics argue that violates the Voting Rights Act by putting a heavy burden on minorities who may not have IDs.
But South Carolina isn't the only state with new voting laws. In the past two years alone, 19 states have introduced new voting laws.
For a closer look at what that could mean in this year's race, we're joined by NPR's Senior Washington Editor Ron Elving.
