A slew of GOP-controlled state legislatures passed strict voter ID laws over the last two years that require voters to bring specified identification to the polls to vote.
“Today, racism and inequality does not manifest itself in a white sheet, Jim Crow laws, poll taxes or barking dogs," Campbell said. "But the dogs are still biting in other ways.”
