Earl Leroy Brewer was the Governor of Mississippi from 1912 to 1916. Elected as a Democrat, he was unopposed in the primary and won the governorship without ever making a single public campaign speech.

Theodore Gilmore Bilbo was an American politician who twice served as governor of Mississippi and later was elected a U.S. Senator (1935–1947). A demagogue and lifelong Democrat, he was a filibusterer whose name was synonymous with white supremacy. Like many Southern Democrats of his era, Bilbo believed that black people were inferior; he defended segregation, and was a member of the Ku Klux Klan, the United States' most notable white supremacist terrorist organization. He also published a pro-segregation work, Take Your Choice: Separation or Mongrelization.
