The 1976 United States Senate elections was an election for the United States Senate. Held on November 2, the 33 seats of Class 1 were contested in regular elections. They coincided with Democrat Jimmy Carter's presidential election and the United States Bicentennial celebration. Although almost half of the seats decided in this election changed parties, Carter's narrow victory did not provide coattails for the Democratic Party.
The 1972 United States Senate elections were held on November 7, with the 33 seats of Class 2 contested in regular elections. They coincided with the landslide re-election of Republican President Richard Nixon. Despite Nixon's landslide victory, Democrats increased their majority by two seats. The Democrats picked up open seats in Kentucky and South Dakota, and defeated four incumbent senators: Gordon Allott of Colorado, J. Caleb Boggs of Delaware, Jack Miller of Iowa, and Margaret Chase Smith of Maine. The Republicans picked up open seats in New Mexico, North Carolina, and Oklahoma, and defeated one incumbent, William B. Spong Jr. of Virginia.
The 1970 United States Senate elections was an election for the United States Senate. It took place on November 3, with the 33 seats of Class 1 contested in regular elections. Special elections were also held to fill vacancies. These races occurred in the middle of Richard Nixon's first term as president. The Democrats lost a net of three seats, while the Republicans and the Conservative Party of New York picked up one net seat each, and former Democrat Harry F. Byrd Jr. was re-elected as an independent.
The 1964 United States Senate elections were held on November 3. The 33 seats of Class 1 were contested in regular elections. Special elections were also held to fill vacancies. They coincided with the election of President Lyndon B. Johnson by an overwhelming majority, to a full term. His Democratic Party picked up a net two seats from the Republicans. As of 2022, this was the last time either party has had a two-thirds majority in the Senate, which would have hypothetically allowed the Senate Democrats to override a veto, propose constitutional amendments, or convict and expel certain officials without any votes from Senate Republicans. In practice, however, internal divisions effectively prevented the Democrats from doing so. The Senate election coincided with Democratic gains in the House in the same year.
The 1958 United States Senate elections were elections for the United States Senate which occurred in the middle of President Dwight D. Eisenhower's second term. Thirty-two seats of Class 1 were contested in regular elections, the new state of Alaska held its first Senate elections for its Class 2 and 3 seats, and two special elections were held to fill vacancies.
The 1954 United States Senate elections was a midterm election in the first term of Dwight D. Eisenhower's presidency. The 32 Senate seats of Class 2 were contested in regular elections, and six special elections were held to fill vacancies. Eisenhower's Republican party lost a net of two seats to the Democratic opposition. This small change was just enough to give Democrats control of the chamber with the support of an Independent who caucused with them.
The 1924 United States Senate elections were elections for the United States Senate which coincided with the election of Republican President Calvin Coolidge to a full term. The 32 seats of Class 2 were contested in regular elections, and special elections were held to fill vacancies. The strong economy and Coolidge's popularity helped Republican candidates increase their majority by 3.
Thomas James Walsh was an American lawyer and Democratic Party politician from Helena, Montana who represented Montana in the US Senate from 1913 to 1933. He was initially elected by the state legislature, and from 1918 on by popular vote, in keeping with the requirements of the Seventeenth Amendment to the United States Constitution.
The United States Senate election of 1924 in Massachusetts was held on November 4, 1924. Incumbent Democratic Senator David I. Walsh, first elected in 1918, ran for a second term in office but was defeated by the Republican nominee incumbent Speaker of the U.S. House Frederick H. Gillett. Despite winning 13 out of 14 counties in the state, Gillett was only able to win a narrow margin of 1.7%, which was largely due to Walsh's strong performance in Suffolk County, home to the state capitol of Boston, likely being carried over by fellow Republican Calvin Coolidge's strong performance in the 1924 United States presidential election.
The 1918 United States Senate election in Montana took place on November 5, 1918. Incumbent United States Senator Thomas J. Walsh, who was first elected to the Senate in 1912, ran for re-election.

Lanstrum, a former State Representative and the Republican nominee, and Jeannette Rankin, one of two United States representatives from Montana's at-large congressional district and the nominee of the National Party. Walsh narrowly won his second term in the Senate.

Erickson, who, as governor, had appointed himself to the seat in 1933 upon the death of Thomas J. Walsh, ran for re-election. However, he was defeated in the Democratic primary by James E. Murray, who was the former Silver Bow County Attorney and the Chairman of the State Advisory Board of the Public Works Administration. In the general election, Murray defeated Scott Leavitt, a former United States Congressman who had represented Montana's 2nd congressional district, and an independent candidate in a landslide to win his first term in the Senate.

Murray, who was first elected to the Senate in a special election in 1934 and was re-elected in 1936, ran for re-election.

Rankin, the Republican nominee and brother of representative Jeannette Rankin. In a closely fought election, Murray narrowly defeated Rankin to win re-election to his third term and his second full term in the Senate.

The 1922 United States Senate election in Montana took place on November 7, 1922. Incumbent United States Senator Henry L. Myers, who was first elected to the Senate in 1910, and was re-elected in 1916, declined to seek re-election. Former United States Attorney Burton K. Wheeler won the Democratic primary and advanced to the general election, where he faced Carl W. Riddick, the United States Congressman from Montana's 2nd congressional district and the Republican nominee. Ultimately, Wheeler defeated Riddick comfortably and won his first term in the Senate.
The 1928 United States Senate election in Montana took place on November 6, 1928. Incumbent United States Senator Burton K. Wheeler, who was first elected to the Senate in 1922, ran for re-election. After successfully defeating several challengers in the Democratic primary, Wheeler advanced to the general election, where he faced Republican nominee Joseph M. Dixon, the former Governor of Montana who had previously served in the United States Senate from 1907 to 1913. Though the election was closer than Wheeler's first election, he still managed to defeat Dixon to win his second term in the Senate.

Erickson, who was first elected governor in 1924 and was re-elected in 1928, ran for re-election. He won the Democratic primary with a plurality and advanced to the general election, where he faced Frank A. Hazelbaker, the Lieutenant Governor of Montana. Despite the fact that Franklin D. Roosevelt carried the state in a landslide in the presidential election that year, Erickson only narrowly defeated Hazelbaker to win re-election to his third and final term as governor, though he would later resign just a few months into his term to appoint himself to the United States Senate.
The 1916 Montana gubernatorial election took place on November 7, 1916. Incumbent Governor of Montana Sam V. Stewart, who was first elected governor in 1912, ran for re-election.
