However, this was reduced to 67-33 between the election and the next Congress, as on November 18, 1962, Democrat Dennis Chávez, who was not up for election that year, died.

The 1912–13 United States Senate elections were held on various dates in various states. They were the last U.S. Senate elections before the ratification of the Seventeenth Amendment in 1913, establishing direct elections for all Senate seats. Senators had been primarily chosen by state legislatures. Senators were elected over a wide range of time throughout 1912 and 1913, and a seat may have been filled months late or remained vacant due to legislative deadlock. Some states elected their senators directly even before passage of Seventeenth Amendment. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.
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.

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 in an election where other candidates had ballot access. A Senate election where the victor won by a write-in campaign would not happen again until 2010.
