"A quick refresher: The Voting Rights Act outlaws racial discrimination against voters. But the law's real strength comes from its "preclearance" provision, which forces jurisdictions with a history of racial discrimination to submit new voting measures to the federal government for approval.
In last summer's Shelby County v. Holder ruling, the Supreme Court threw out the part of the law that spelled out when states were automatically subject to federal oversight. States that have been released from preclearance have already passed a rash of new restrictive voting measures."
