A federal judge has set a 10 a.m. Friday hearing in Savannah over a lawsuit seeking to reopen Georgia’s voter registration due to Hurricane Matthew. Voter advocates filed the suit Wednesday just before midnight, arguing that an emergency extension of the registration deadline was needed because some coastal residents forced to flee last weekend’s storm did not have enough opportunity to submit applications. The suit requests an extension through Oct. 18 for residents of Chatham County, where local government offices were closed for what would have been the last six days of the voter registration period that ended on Tuesday. It also suggests that the extension could be made available to residents statewide.
