Last year, Georgia passed its “exact match” law, which requires that people’s name on their government-issued IDs must accurately match the name on the voter rolls, but according to a new report by the Washington Post, hundreds of thousands of voters may not able to vote in the upcoming midterm elections because of the law.

Brian Kemp, Georgia’s Secretary of State and Republican candidate for governor, has not processed over 53,000 voter registration applications because of mismatches in the name between their voting records such as driver’s licenses and Social Security cards, per the report.

Critics have accused Kemp of voter suppression because some people don’t have proper photo ID and has prompted Georgia’s NAACP to file a lawsuit alleging that the move will stop many racial minorities from voting.

Thirty percent of Georgia voters did not fit the “exact match” criterion, which comes out to 909,540 eligible voters being disenfranchised, per the Washington Post study.

According to an algorithm created for the study, which didn’t use Georgia’s “exact match” policy, around 91 percent of voters would be eligible to vote.
