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.
Gladys Shields Pyle was an American educator, politician and the first woman elected to the United States Senate without having previously been appointed to her position; she was also the first female senator to serve as a Republican and the first female senator from South Dakota. Further, she was the first female senator from outside the south. She was also the first unmarried female senator.
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 1948 United States Senate election in Maine was held on September 13, 1948. Incumbent Republican U.S. Senator and Senate Majority Leader Wallace White did not seek a fourth term in office.
The 1932 United States Senate election in South Dakota took place on November 8, 1932. Incumbent Republican Senator Peter Norbeck ran for re-election to a third term. After easily turning back a challenge from former State Senator Harry F. Brownell in the Republican primary, Norbeck faced attorney Ulysses Simpson Grant Cherry, the Democratic nominee, in the general election. Owing in part to Franklin D. Roosevelt's landslide victory in South Dakota, the race was much closer than it was in 1926, but Norbeck still defeated Cherry by a decisive margin to win his third, and final, term. Norbeck died in office on December 20, 1936, triggering a special election in 1938.
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 1950 United States Senate election in South Dakota took place on November 7, 1950. Incumbent Republican senator Chan Gurney ran for re-election to a third term. He was challenged in the Republican primary by Congressman Francis H. Case, who had represented the 2nd District since 1939. In the general election, Case faced John A. Engel, an attorney and the 1948 Democratic nominee for the U.S. Senate. As the Republican Party was making significant gains nationwide, Case defeated Engel in a landslide.
The 1920 United States Senate election in South Dakota took place on November 2, 1926. Incumbent Republican Senator Peter Norbeck ran for re-election to a second term. In the Republican primary, he faced former State Senator George J. Danforth, who had the support of Governor Carl Gunderson in an intra-party split between Norbeck and Gunderson. Norbeck defeated Danforth by a wide margin, and then faced former State Representative Charles J. Gunderson in the general election. Norbeck defeated Gunderson in a landslide to win re-election.
The 1930 United States Senate election in South Dakota took place on November 4, 1930. Incumbent Republican Senator William H. McMaster ran for re-election to a second term. After beating back a challenge in the Republican primary from former State Senator George J. Danforth, McMaster faced Democratic nominee William J. Bulow, the incumbent Governor, in the general election. As the Democratic Party performed well nationwide, Bulow narrowly defeated McMaster.
The 1936 United States Senate election in South Dakota took place on November 3, 1936. Incumbent Democratic Senator William J. Bulow ran for re-election to a second term. He was challenged by businessman Chan Gurney, who defeated former Congressman Charles A. Christopherson in the Republican primary. Bulow, likely aided by President Franklin D. Roosevelt's landslide victory in South Dakota, narrowly defeated Gurney to win his second term, though he significantly underperformed Roosevelt.
The 1932 United States Senate election in South Dakota took place on November 7, 1944. Incumbent Republican Senator Chan Gurney ran for re-election to a second term. He faced a strong challenge in the Republican primary from Lieutenant Governor A. C. Miller, who claimed that Gurney was too friendly to New Deal policies, but was defeated by Gurney by a wide margin. In the general election, Gurney faced former State Senator George M. Bradshaw, whom he defeated in a landslide as Thomas E. Dewey was decisively winning the state over President Franklin D. Roosevelt in the presidential election.
The 1968 United States Senate election in South Dakota took place on November 5, 1968. Incumbent Democratic Senator George McGovern ran for re-election to a second term. He was challenged by former Governor Archie M. Gubbrud, who was persuaded to enter the race by the South Dakota Republican establishment. McGovern defeated Gubbrud by a wide margin, even as Richard Nixon was defeating Hubert Humphrey in the state's presidential election in a landslide.
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 1918 South Dakota gubernatorial election was held on November 5, 1918. Incumbent Republican Governor Peter Norbeck ran for re-election to a second term. He won the Republican primary unopposed and faced Nonpartisan League candidate Mark P. Bates, a farmer, and Democratic nominee James E. Bird in the general election. Norbeck's share of the vote decreased from 1916 to 53%, but he benefited from the split field. Bates placed second with 26% of the vote, while Bird placed third with 19% of the vote.
The 1920 South Dakota gubernatorial election was held on November 2, 1920. Incumbent Republican Governor Peter Norbeck declined to run for re-election, instead choosing to run for the U.S. Senate. Lieutenant Governor William H. McMaster won the Republican primary and advanced to the general election, where he faced Nonpartisan League candidate Mark P. Bates and former State Senator William W. Howes, the Democratic nominee. The election was largely a replay of the 1918 election, with McMaster winning a large victory, Bates coming in second, and Howes coming in a distant third.
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 1936 South Dakota gubernatorial election was held on November 3, 1936. Incumbent Democratic Governor Tom Berry ran for re-election to a third term, the first Governor of South Dakota to do so. Berry was challenged by Republican Leslie Jensen, the former Collector of Internal Revenue for the state of South Dakota. Both Berry and Jensen won their primaries uncontested and advanced to the general election. Some drama surrounded the potential candidacy of Democratic State Auditor George O'Neill as an independent candidate for Governor or, in the alternative, his cross-party endorsement of Jensen; after initially announcing his campaign and hedging, O'Neill dropped out of the race in September and endorsed the Democratic ticket in the state, including Berry.
