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.
The 1894 South Dakota gubernatorial election was held on November 6, 1894. Incumbent Republican Governor Charles H. Sheldon ran for re-election to a second term. Despite facing a thread of defeat at the Republican convention, Sheldon was renominated unanimously. In the general election, he faced Populist nominee Isaac Howe, a Spink County Judge; James A. Ward, the former state chairman of the South Dakota Democratic Party; and Prohibition nominee M. D. Alexander. The election was largely a replay of the gubernatorial elections of 1890 and 1892, with the Farmers' Alliance candidate placing second and the Democratic nominee placing a distant third. This time, however, Sheldon won an outright majority and the Democratic Party's vote share shrunk to just 11%, its worst performance in state history.
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 1902 South Dakota gubernatorial election was held on November 4, 1902. Incumbent Republican Governor Charles N. Herreid ran for re-election to a second term. He faced former Watertown Mayor John W. Martin, the Fusion nominee who was listed as the Democratic nominee, in the general election. Herreid defeated Martin in a landslide to win his second term.
The 1904 South Dakota gubernatorial election was held on November 8, 1904. Incumbent Republican Governor Charles N. Herreid declined to run for re-election to a third term. Clark County State's Attorney Samuel H. Elrod won the Republican nomination to run as Herreid's successor, and he faced Democratic nominee Louis N. Crill, the former President of the State Senate, and former U.S. Congressman Freeman Knowles, the Socialist nominee. For the first time since 1894, the Democratic and Populist Parties nominated separate candidates. Ultimately, the split in the two parties did not prove dispositive; Elrod defeated Crill and the other candidates in a landslide.
The 1906 South Dakota gubernatorial election was held on November 6, 1906. Incumbent Republican Governor Samuel H. Elrod ran for re-election, but was defeated for renomination at the Republican convention by former Attorney General Coe I. Crawford. In the general election, Crawford was opposed by the Democratic nominee, former State Representative John A. Stransky of Brule County. Crawford had little difficulty defeating Stransky in a landslide, largely matching Elrod's margin of victory from two years earlier.
The 1924 United States Senate election in South Dakota took place on November 4, 1924. Incumbent Senator Thomas Sterling ran for re-election to a third term, but he was defeated in the Republican primary by Governor William H. McMaster. In the general election, McMaster was opposed by attorney Ulysses Simpson Grant Cherry, the Democratic nominee, and several independent candidates. McMaster defeated his opponents by a wide margin, but fell far short of a majority, winning only 44% of the vote.
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 1954 United States Senate election in South Dakota took place on November 2, 1954. Incumbent Republican Senator Karl E. Mundt ran for re-election to his second term. He was opposed by former State Representative Kenneth Holum, the Democratic nominee. Mundt defeated Holum in a landslide to win re-election.
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 1914 South Dakota gubernatorial election was held on November 3, 1914. Despite a close election in 1912, incumbent Republican Governor Frank M. Byrne defeated Democratic nominee James W. McCarter, an Edmunds County Judge, with 50.07% of the vote. Coincidently, Bryne's Democratic opponent in 1912, Edwin S. Johnson, was elected the same year to represent South Dakota in the United States Senate.
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 1926 South Dakota gubernatorial election was held on November 2, 1926. Incumbent Republican Governor Carl Gunderson ran for re-election to a second term. The election was largely a rematch of the 1924 election, with Gunderson's chief opponent from two years prior, Democrat William J. Bulow, challenging him once again. Two other candidates—Farmer–Labor nominee Tom Ayres and Pierre Mayor John E. Hipple, an independent—also ran. Though the left-leaning vote was split, Bulow was still able to win a decisive victory over Gunderson, whose support from two years earlier had completely collapsed.
The 1928 South Dakota gubernatorial election was held on November 6, 1928. Incumbent Democratic Governor William J. Bulow ran for re-election to a second term. In the general election, he faced Attorney General Buell F. Jones, the Republican nominee. Despite Republican presidential nominee Herbert Hoover overwhelmingly defeating Democratic nominee Al Smith overwhelmingly in South Dakota, Bulow defeated Jones by a decisive margin to retain the governorship. In so doing, he became the first Democratic candidate for Governor to receive a majority of the vote in the state's history.
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 1940 South Dakota gubernatorial election was held on November 5, 1940. Incumbent Republican Governor Harlan J. Bushfield sought re-election to a second term. After winning the Republican primary by a large margin, he faced Democrat Lewis W. Bicknell, former Day County State's Attorney, in the general election. Though Bushfield underperformed Republican presidential nominee Wendell Willkie, who won the state in a landslide, he nonetheless defeated Bicknell by a wide margin to easily win re-election.
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.
