On Thursday, several civil rights and voting advocacy groups sued Georgia Secretary of State Brian Kemp to halt enforcement of the state's "exact match" voting law. Kemp, who's also Georgia's Republican nominee for governor, has put on hold 53,000 voter registration applications, and the lawsuit says he's using the law to suppress minority turnout in his race against Democrat Stacey Abrams, who is black. Kemp blames the large racial disparity in the makeup of the suspended applications on sloppy work by the voter registration organization Abrams started in 2014. People whose applications were put in limbo under the "exact match" policy can still vote with a state-issued ID or provisional ballot, though critics say that provision is confusing and poorly communicated.
