Kemp breaks his promises doesn't mean anyone else should." Two days before the election, Kemp's office announced that it was investigating the Georgia Democratic Party for unspecified "possible cybercrimes"; the Georgia Democratic Party stated that "Kemp's scurrilous claims are 100 percent false" and described them as a "political stunt". A 2020 investigation by the Georgia attorney general's office concluded that there was no evidence of computer crimes. Later that year, it was revealed that the alleged cybercrime against Kemp's office was in fact a planned security test that one of Kemp's staff members had signed off on three months prior. As Georgia's secretary of state, Kemp was in charge of elections and voter registration during the election. Kemp was accused of voter suppression during the election between him and Abrams. Emory University professor Carol Anderson has criticized Kemp as an "enemy of democracy" and "an expert in voter suppression" for his actions as secretary of state. Political scientists Michael Bernhard and Daniel O'Neill described Kemp's actions in the 2018 gubernatorial election as the worst case of voter suppression in that election year. Election law expert Rick L. Hasen described Kemp as "perhaps the most incompetent state chief elections officer" in the 2018 elections, pointing to a number of actions that jeopardized Georgia's election security and made it harder for eligible voters to vote. Hasen writes that it was "hard to tell" which of Kemp's "actions were due to incompetence and which were attempted suppression." Between 2012 and 2018, Kemp's office canceled over 1.4 million voter registrations, with nearly 700,000 cancellations in 2017 alone. On a single night in July 2017, half a million voters had their registrations canceled. According to The Atlanta Journal-Constitution, election-law experts said that this "may represent the largest mass disenfranchisement in US history." Kemp oversaw the removals as secretary of state, and did so eight months after he declared his candidacy for governor. An investigative journalism group run by Greg Palast found that of the approximately 534,000 Georgians whose voter registrations were purged between 2016 and 2017, more than 334,000 still lived where they were registered. The voters were given no notice that they had been purged. Palast sued Kemp, claiming over 300,000 voters were purged illegally. Kemp's office denied any wrongdoing, saying that by "regularly updating our rolls, we prevent fraud and ensure that all votes are cast by eligible Georgia voters." By early October
