Georgia's strict system for adding new voters to the rolls risks disenfranchising tens of thousands of minorities in the battleground state this fall, according to a new lawsuit by several voting rights groups.

Since July 2013, Georgia has failed to process more than 42,000 voter registration applications because the personal information provided didn't exactly match existing information in state-maintained databases, lawyers for the groups said. Over 86 percent of those whose applications weren't processed were non-white, even though whites have made up nearly half of those who have sought to register during that period.

The lawsuit, filed Wednesday in federal court, charges that the "exact match" system used by Georgia Secretary of State Brian Kemp violates the Voting Rights Act's ban on racial discrimination in voting. It asks that the state be required to stop using the system immediately, while there's still time for affected applicants to be added to the rolls.

"Georgia, like many states across the country, has erected another burdensome and unnecessary obstacle for those seeking to register and vote," said Kristen Clarke, president and executive director of the Lawyers' Committee for Civil Rights Under Law, one of the lead groups behind the suit. "The Secretary of State's exact-match program penalizes those seeking to register and vote because of errors contained in databases maintained by the state."

Kemp's office says it's following the law.
