"Go Bo" was the persistent Callaway campaign slogan. Some liberals, disgruntled with both party nominees, proclaimed, "Go Bo, and take Lester with you." Some of these individuals organized a write-in campaign on behalf of Ellis Arnall, who said that he neither encouraged nor discouraged their undertaking. Maddox likened the write-in to an attempt to "slip into the back door like a thief in the night" and called upon Arnall to renounce the drive. Several celebrities endorsed the Arnall write-in, including television personality Hugh Downs and singers Peter, Paul, and Mary, Frank Sinatra, and Sammy Davis, Jr. The Georgia civil rights activist Hosea Williams challenged Callaway on a myriad of issues important to liberals and claimed that the Republican nominee had purchased the endorsement of the "Atlanta Journal."
