In 2013, Kelli Griffin went to vote in a local election in Montrose, Iowa. She had been through some hard times — a survivor of domestic abuse who had suffered from drug addiction, she was convicted in 2008 of a drug-related crime, and served five years probation. But now Griffin was turning her life around, and voting was a rite of passage. She even took her four kids to the polls to teach them about the democratic process. “I felt good,” said Griffin, 41. “I mean, it’s one of the steps to being back into society, to fulfilling that I am just like everybody else. I mean, I’ve overcome a lot.” But what happened next would make clear that in the eyes of the law, Griffin wasn’t at all like everybody else. It would set this shy stay-at-home mom who never graduated college on a path to challenging her state’s highest officials. And it would help spark the latest step in a growing push-back against a set of laws that, five decades after the passage of the Voting Rights Act, still disenfranchise millions of Americans.
