The South Carolina Democratic Party held the primary on August 27 and William P. Pollock had a slight lead, but did not garner over 50% of the vote and was forced into a runoff election against Thomas H. Peeples. On September 10, Pollock won the runoff and was thereby elected for the short term in the Senate because there was no opposition to the Democratic candidate in the general election.
