Senator Coleman Livingston Blease was opposed in the Democratic primary by former RepresentativeJames F. Byrnes. Blease was the leader in the first primary election on August 26, but in previous primary elections he had been the leader in the first primary and unable to increase his support in the runoff election. This election was no different and Byrnes won the runoff on September 9. There was no opposition to the Democratic candidate in the general election so Byrnes was elected to a six-year term in the Senate.
