Howard Hollis "Bo" Callaway (April 2, 1927[2] – March 15, 2014) was an American businessman and politician.

The election was exceptionally close due to a split within the state Democratic Party between supporters of segregationist Lester Maddox and liberal former governor Ellis Arnall; after Maddox won the Democratic nomination, Arnall continued his campaign as a write-in candidate.

As Army Secretary, Callaway entered into a prominent national controversy when he first reduced the sentence of and later paroled Lieutenant William Calley for his role in the My Lai massacre.

[9][10] Callaway served as Ford's campaign manager,[11] but resigned following accusations that he had used undue political influence to ensure the expansion of a ski resort;[11] he was replaced by Rogers Morton.

He was supported by Senator William L. Armstrong, but ultimately lost the nomination to Mary Estill Buchanan.
