The Democratic primary election was held on August 13, 1974, but as no candidate received a majority of the vote, a run-off election was held between former member of the Georgia State Senate Zell Miller and Mary Hitt on September 3, 1974. Candidate Zell Miller received a majority of the votes (60.82%) in the run-off election against Hitt, and was thus elected as the nominee for the general election.[1]
