David Gans in WaPo:
Today, the Voting Rights Act that King helped to push through Congress is in tatters. To stop voting discrimination, the Voting Rights Act created strong remedies applicable to jurisdictions with a long history of flouting constitutional guarantees. Such jurisdictions would have to “preclear” new voting changes and prove they were nondiscriminatory before enforcing them. In 2013, in a 5-4 ruling in Shelby County v. Holder, the Supreme Court eliminated this critical remedy. Claiming that things had changed, Chief Justice John G. Roberts Jr. insisted that the Voting Rights Act’s coverage formula was now unconstitutional.
