Next week, state attorney general Alan Wilson will attempt to contest the U.S. Dept. of Justice’s rejection of South Carolina’s “voter ID” law. The case is taking a new twist, however, thanks to the AG of another state. Today, Arizona’s Thomas Horne filed an amicus brief with the Supreme Court, claiming that one particular part of the Voting Rights Act unfairly affects the nine states that are subject to its laws. Section Five of the Act notes that any change to voting laws in subject states must be approved by the federal government. Some other states not subject to VRA, though, have already changed their own laws pertaining to voting and didn’t require federal approval for those changes, Horne notes. Different formats of voter identification requirements are used in some of those other states, Horne notes, and the federal government didn’t interfere in those cases. Minority voters are still subject to discrimination in those states, too, he says. Because South Carolina and nine other states are the only ones subject to the Voting Rights Act, Horne concludes, it has unfairly lost its own right to discriminate. Section Five of the VRA “undermines the principal of equal sovereignty,” he says.
