The 1938 United States Senate elections occurred in the middle of Franklin D. Roosevelt's second term. The 32 seats of Class 3 were contested in regular elections, and special elections were held to fill vacancies. The Republicans gained eight seats from the Democrats, though this occurred after multiple Democratic gains since the 1932 election, leading to the Democrats retaining a commanding lead over the Republicans with more than two-thirds of the legislative chamber.
William Henry McMaster was an American politician who served as the tenth Governor of South Dakota from 1921 until 1925. A member of the Republican Party, he went on to serve as a member of the United States Senate from South Dakota from 1925 to 1931.
Thomas Matthew Berry was the 14th Governor of South Dakota. Berry, a Democrat from Belvidere, South Dakota, served from 1933 to 1937. He is noted for defeating two incumbent Democratic United States senators in the state Democratic primary and then losing the seat to the Republicans in the general election.
Herbert Emery Hitchcock was a United States senator from South Dakota.
The 1892 South Dakota gubernatorial election was held on November 8, 1892. Incumbent Republican Governor Arthur C. Mellette declined to seek re-election to a third term. Former territorial legislator Charles H. Sheldon was nominated by the Republican Party as Mellette's replacement, and he faced former legislator Abraham Lincoln Van Osdel, a leader in the South Dakota Farmers' Alliance and the nominee of the Independent Party, along with Democratic nominee Peter Couchman, in the general election. The result was largely a replay of the 1890 election, with Sheldon winning by a large margin, but only a plurality, and Van Osdel taking second place over Couchman.
The 1896 South Dakota gubernatorial election was held on November 3, 1896. Incumbent Republican Governor Charles H. Sheldon declined to run for re-election to a third term. Former Secretary of State Amund O. Ringsrud was nominated as Sheldon's replacement at the Republican convention. Ringrud's main opponent was businessman Andrew E. Lee, who was nominated by a makeshift coalition of Populists, Free Silver Republicans, and Democrats. In the general election, Lee narrowly defeated Ringsrud, the first defeat for the Republican Party in a gubernatorial election since statehood.
The 1920 United States Senate election in South Dakota took place on November 2, 1920. Incumbent Democratic Senator Edwin S. Johnson declined to seek re-election to a second term. In the Democratic primary, attorney Ulysses Simpson Grant Cherry defeated former State Senator Louis Napoleon Crill and former U.S. Marshal Tom Taubman, while in the Republican primary, Governor Peter Norbeck defeated former State Supreme Court Justice Dick Haney. In the general election, Cherry and Norbeck faced a litany of independent candidates, including Nonpartisan League candidate Tom Ayres. Benefiting from the split in left-wing candidates, Norbeck won by a wide margin, with Ayres narrowly beating out Cherry for second place.
The 1942 United States Senate election in South Dakota took place on November 3, 1942. Incumbent Democratic Senator William J. Bulow ran for re-election to a third term. During the primary, Bulow was attacked for being insufficiently supportive of President Franklin Roosevelt's foreign policy and war preparedness. Former Governor Tom Berry, Bulow's chief opponent, drew a contrast between Bulow's isolationism and his support for Roosevelt's policies. In the end, Berry defeated Bulow in a landslide, and advanced to the general election, where he faced Harlan J. Bushfield, the incumbent Republican Governor of South Dakota. As Republicans gained ground nationwide, Bushfield defeated Berry in a landslide to pick up the seat for the Republican Party. Bushfield did not serve his full term, however; shortly before the 1948 U.S. Senate election, he died.
The 1956 United States Senate election in South Dakota took place on November 6, 1956. Incumbent Republican Senator Francis H. Case ran for re-election to a second term. In the general election, Case was opposed by former State Representative Kenneth Holum, who was the 1954 Democratic nominee for the U.S. Senate. Owing in part to anger among the state's farmers, the race between Case and Holum was quite close, with Holum leading Case on election night and only falling behind the next day. Case ended up narrowly winning re-election, defeating Holum by just 4,620 votes.
The 1962 United States Senate election in South Dakota took place on November 6, 1962. Incumbent Republican Senator Francis H. Case ran for re-election to a third term. He won the Republican primary against Attorney General A. C. Miller, but shortly after the primary, died. The Republican State Central Committee named Lieutenant Governor Joseph H. Bottum as Case's replacement on the ballot, and Governor Archie Gubbrud appointed Bottum to fill the vacancy caused by Case's death. In the general election, Bottum was opposed by Democratic nominee George McGovern, the Director of Food for Peace and the former U.S. Congressman from South Dakota's 1st congressional district. The contest between Bottum and McGovern was quite close, with McGovern narrowly defeating him for re-election by just 597 votes, making him the first Democrat to win a Senate election in South Dakota since William J. Bulow's win in 1936.
The 1912 South Dakota gubernatorial election was held on November 5, 1912. Incumbent Republican Governor Robert S. Vessey declined to run for re-election to a third term. Lieutenant Governor Frank M. Byrne won the Republican primary to succeed Vessey, and then faced State Senator Edwin S. Johnson, the Democratic nominee, in the general election. Byrne only narrowly defeated Johnson, winning just 49% of the vote to Johnson's 46%, the closest gubernatorial election since 1898.
The 1950 South Dakota gubernatorial election was held on November 7, 1950. Incumbent Republican Governor George T. Mickelson was unable to seek re-election to a third term due to newly imposed term limits. Accordingly, a competitive race to replace him ensued. Attorney General Sigurd Anderson won a slim plurality in the Republican primary, barely exceeding 35% and narrowly avoiding having the Republican nomination sent to the state party convention. In the general election, Anderson faced State Representative Joe Robbie. Anderson easily defeated Robbie, winning his first term with 61% of the vote to Robbie's 39%.
The 1948 South Dakota gubernatorial election was held on November 2, 1948. Incumbent Republican Governor George T. Mickelson ran for re-election to a second term. He was opposed by Democrat Harold J. Volz, a businessman and the former Chairman of the Tripp County Democratic Party. Both Mickelson and Volz were the only candidates of their parties to file for Governor, ensuring that they won their respective nominations unopposed and removing the race from the primary ballot. In the general election, Mickelson had little difficulty defeating Volz. Though Republican presidential nominee Thomas E. Dewey only narrowly won the state over President Harry S. Truman, Mickelson's popularity allowed him to win re-election in a landslide, receiving 61% of the vote to Volz's 39%.
The 1916 South Dakota gubernatorial election was held on November 7, 1916. Incumbent Republican Governor Frank M. Byrne declined to seek re-election to a third term. Lieutenant Governor Peter Norbeck won the Republican primary to succeed him, and in the general election faced State Representative Orville V. Rinehart. Norbeck won his first term as Governor in a landslide over Rinehart.
The 1938 United States Senate elections in South Dakota took place on November 8, 1938. Incumbent Republican Senator Peter Norbeck died in office on December 20, 1936. Herbert E. Hitchcock was appointed by Governor Tom Berry as Norbeck's replacement. Two elections for the same Senate seat were held on the same day; one as a special election to fill the remainder of Norbeck's six-year term, and another to select a Senator to serve the next six-year term.
The 1924 South Dakota gubernatorial election was held on November 4, 1924. Incumbent Republican Governor William H. McMaster declined to run for re-election to a third term, instead opting to run for the U.S. Senate. Lieutenant Governor Carl Gunderson won the Republican primary unopposed. In the general election, he faced three prominent opponents: Democratic nominee William J. Bulow, a former State Senator and Mayor of Beresford; Farmer–Labor nominee A. L. Putnam; and perennial candidate Richard O. Richards. Gunderson. With the left-leaning vote split, Gunderson won the election in a landslide.
The 1930 South Dakota gubernatorial election was held on November 4, 1930. Incumbent Democratic Governor William J. Bulow declined to run for re-election to a third term, instead opting to successfully run for the U.S. Senate. The Republican nomination was hard-fought and the primary was crowded; because no candidate received 35% of the vote, state law required that the nomination be decided at a state party convention. There, former State Senator Warren Green, the last-place finisher in the primary, defeated Secretary of State Gladys Pyle, the plurality winner. In the general election, Green faced D. A. McCullough, the state's Rural Credits Commissioner and the Democratic nominee. Despite Bulow's success in the preceding two elections, Green defeated McCullough by a decisive margin—even as Bulow himself was elected to the U.S. Senate.
The 1932 South Dakota gubernatorial election was held on November 8, 1932. Incumbent Republican Governor Warren Green ran for re-election to a second term. He defeated former Governor Carl Gunderson in the Republican primary and faced former State Representative Tom Berry, the Democratic nominee, in the general election. Aided by Democratic presidential nominee Franklin D. Roosevelt's landslide victory in South Dakota, Berry defeated Green for re-election in a landslide.
The 1938 South Dakota gubernatorial election was held on November 8, 1938. Incumbent Republican Governor Leslie Jensen declined to seek re-election and instead unsuccessfully ran for the U.S. Senate. Harlan J. Bushfield, the former Chairman of the South Dakota Republican Party, won the Republican primary to succeed Jensen. In the general election, he faced Democratic nominee Oscar Fosheim, a State Representative from Miner County, in the general election. Bushfield defeated Fosheim by a relatively close margin, winning his first term as governor.
The 1942 South Dakota gubernatorial election was held on November 3, 1942. Incumbent Republican Governor Harlan J. Bushfield declined to seek re-election to a third term and instead successfully ran for the U.S. Senate. A crowded Republican primary developed to succeed him, and because no candidate received 35% of the vote, the nomination was decided at the state Republican convention, where former Attorney General Merrell Q. Sharpe, the second-place finisher in the primary, won the nomination. In the general election, Sharpe faced Democratic nominee Lewis W. Bicknell, the 1940 Democratic nominee for Governor. Aided by the national Republican landslide, Sharpe defeated Bicknell in a landslide.
