to persuade him not to run, warning that due to his failing health that a grueling campaign might kill him, but he refused to step aside in favor of his son Herman who had been groomed as his heir, saying "Naw, I'm the only goddamn son of a bitch who can win". Talmadge's campaign was noted for its violent racist rhetoric as he boasted about assaulting and flogging the black sharecroppers who worked for his family as a young man and he claimed to have chased a black man down the street with an ax because he sat next to a white woman. In June 2007, previously sealed FBI files revealed that Talmadge was investigated by the FBI over suspicions he sanctioned the Moore's Ford lynching. Though Talmadge was unpopular in the more populous urban areas, his relative popularity in rural areas gave him a fighting chance of still winning the Democratic nomination under the "county unit votes" system in which (essentially) the candidate who won the most counties, not the most popular votes, would receive the nomination.

Malcolm, his wife Dorothy, and the other black couple riding in the car, George and Mae Murray Dorsey, were marched out of the car, lined up and shot. The FBI agent investigating the lynching called the allegation that Talmadge led the lynch mob "unbelievable", but he forwarded the allegation to FBI director J.

If y'all are that far off, I feel sorry for you." About the allegations that it was Talmadge who led the lynch mob at Moore's Ford, the historian Robert Pratt stated: "I'm not surprised ... historians over the
