1948 United States Senate elections
Template:Short description Template:Use mdy dates
Template:Infobox election The 1948 United States Senate elections were held concurrently with the election of Democratic President Harry S. Truman for a full term. The 32 seats of Class 2 were contested in regular elections, and one special election was held to fill a vacancy. Truman campaigned against an "obstructionist" Congress that had blocked many of his initiatives, and additionally, the U.S. economy recovered from the postwar recession of 1946–1947 by election day.
Thus, Truman was rewarded with a Democratic gain of nine seats in the Senate, enough to give them control of the chamber. This was the first time since 1936 that Democrats posted a net gain of seats in the chamber.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> This was the last time until 2020 that Democrats flipped a chamber of Congress in a presidential election cycle.

Incumbent United States Senator James E. Murray, who was first elected to the Senate in a special election in 1934 and was re-elected in 1936 and 1942, ran for re-election. After winning the Democratic primary, he faced Tom J. Davis, an attorney and the Republican nominee, in the general election. Following a narrow re-election in 1936, Murray significantly expanded his margin of victory and comfortably won re-election over Davis, winning his fourth term and his third full term in the Senate.

There were 2 elections to the same seat, due to the December 15, 1946 death of three-term Democrat Josiah Bailey. Democratic former congressman William B. Umstead was appointed December 18, 1946 to continue Bailey's term, pending a special election.
Umstead supported the conservative Taft–Hartley Act. The Democratic former Governor of North Carolina J. Melville Broughton was seen as a "rather liberal alternative" to Umstead. Broughton beat Umstead in the Democratic primaries and then won the general elections.

Broughton was seated December 31, 1948 to finish the current term but died March 6, 1949, just after the new term began. His death lead to another appointment (Democrat Frank Graham) in 1949 and another special election in 1950 of Democrat Willis Smith. Smith also died during the term, leading to yet another appointment (Democrat Alton A. Lennon) and 1954 special election (of Democrat W. Kerr Scott). In all, five senators held the seat during the 1949–1955 term.

Senator Burnet R. Maybank was opposed in the Democratic primary by U.S. Representative William Jennings Bryan Dorn and three other candidates. Maybank obtained over 50% in the primary election on August 10 to avoid a runoff election.
| Democratic Primary | ||
|---|---|---|
| Candidate | Votes | % |
| Burnet R. Maybank | 161,608 | 51.5 |
| W.J. Bryan Dorn | 76,749 | 24.4 |
| Neville Bennett | 43,068 | 13.7 |
| Alan Johnstone | 17,689 | 5.6 |
| Marcus A. Stone | 14,904 | 4.8 |
Since the end of Reconstruction in 1877, the Democratic Party dominated the politics of South Carolina and its statewide candidates were never seriously challenged. Maybank did not campaign for the general election as there was no chance of defeat.
