South Carolina (regular)

Johnston:
Main article: 1956 United States Senate election in South Carolina

Incumbent Democrat Olin D. Johnston handily defeated Republican mayor of Clemson Leon P. Crawford. Olin D. Johnston, the incumbent Senator, faced no opposition from South Carolina Democrats and avoided a primary election. Leon P. Crawford, the mayor of the town of Clemson in the Upstate, faced no opposition from South Carolina Republicans and avoided a primary election. Crawford campaigned as a defender of states' rights and denounced Johnston for backing the New Deal and the Fair Deal. The state Republican Party believed that Crawford could have a chance in the election if he galvanized the 128,000 registered black voters, although they were weary of being labeled as the black party. In the end, Johnston remained highly popular with the voters who were still leery of the Republican party and he easily defeated Crawford in the general election.

South Carolina (special)

Thurmond: Main article: 1956 United States Senate special election in South Carolina

The special election resulted from the resignation of Senator Strom Thurmond on April 4, 1956, who was keeping a campaign pledge he had made in the 1954 election. Thurmond was unopposed in his bid to complete the remaining four years of the term. Senator Strom Thurmond faced no opposition from South Carolina Democrats and avoided a primary election. There was a possibility that Governor George Bell Timmerman Jr. might enter the race, but Thurmond was held in such high regard by the voters that there would have been no chance of defeating Thurmond. With no challenge to the remainder of the term, Thurmond did not conduct a campaign and rejoined his old law firm in Aiken until he returned to the Senate after the general election.
