According to records obtained from Kemp's office through a public records request, Appling-Nunez's application —like many of the 53,000 registrations on hold with Kemp's office — was flagged because it ran afoul of the state's "exact match" verification process.
Under the policy, information on voter applications must precisely match information on file with the Georgia Department of Driver Services or the Social Security Administration. Election officials can place non-matching applications on hold.
An application could be held because of an entry error or a dropped hyphen in a last name, for example.
