The 1954 South Carolina United States Senate election was held on November 2, 1954 to select the next U.S. Senator from the state of South Carolina. Senator Burnet R. Maybank did not face a primary challenge in the summer and was therefore renominated as the Democratic Party's nominee for the election in the fall. However, his death on September 1 left the Democratic Party without a nominee and the executive committee decided to nominate state Senator Edgar A. Brown as their candidate for the election. Many South Carolinians were outraged by the party's decision to forgo a primary election and former Governor Strom Thurmond entered the race as a write-in candidate. He easily won the election and became the first U.S. Senator to be elected by a write-in vote (William Knowland of California in 1946 was technically the first, but the ballots in that election were blank with no candidates listed, so essentially every candidate was running a write-in campaign).
Sitting Senator Burnet R. Maybank entered the 1954 contest without a challenge in the Democratic primary nor in the general election. His unexpected death on September 1 caused panic and confusion within the hierarchy of the state Democratic party because the state law required that a party's nominee be certified by September 3. Hours after Maybank's funeral, the state Democratic executive committee met in secret and chose state Senator Edgar A. Brown of Barnwell County as the party's nominee for the general election. Not only was Brown a part of the "Barnwell Ring", but he was also a member of the executive committee.
