The Seventy-second United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1931, to March 4, 1933, during the last two years of Herbert Hoover's presidency. The apportionment of seats in this House of Representatives was based on the Thirteenth Decennial Census of the United States in 1910. The Senate had a Republican majority.

The 1976 United States Senate elections was an election for the United States Senate that coincided with Democratic 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 Democrats, and the balance of the chamber remained the same.
The 1966 United States Senate elections was an election on November 8, 1966 for the United States Senate which occurred midway through the second term of President Lyndon B. Johnson. With divisions in the Democratic base over the Vietnam War, and with the traditional mid-term advantage of the party not holding the presidency, the Republicans took three Democratic seats. Despite Republican gains, the balance remained overwhelmingly in favor of the Democrats, who retained a 64–36 majority. This was also the first election that occurred after the Voting Rights Act of 1965 became law.
The 1964 United States Senate elections 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 2019, this is 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, convict and expel certain officials, or invoke cloture without any votes from Republicans. The Senate election coincided with Democratic gains in the House in the same year.
The 1962 United States Senate elections was an election for the United States Senate which was held in the middle of President John F. Kennedy's term. His Democratic Party made a net gain of three seats from the Republicans, increasing their control of the Senate.

The 1954 United States Senate elections was a midterm election in the first term of Dwight D. Eisenhower's presidency. Eisenhower's Republican party lost a net of two seats to the Democratic opposition.

The 1952 United States Senate elections was an election for the United States Senate which coincided with the election of Dwight D. Eisenhower to the presidency by a large margin. The Republicans took control of the senate by managing to make a net gain of two seats, which was reduced to one when Wayne Morse (R-OR) became an independent.

Norris from the Republican Party to become independent, the Republicans were reduced to 16 seats, the most lopsided Senate since Reconstruction.
The United States Senate elections of 1934 occurred in the middle of Democratic President Franklin D. Roosevelt's first term.

Truman would serve over a decade in the U.S. Senate, before becoming President Roosevelt's third Vice President, before succeeding to the presidency upon the death of President Roosevelt.
The United States Senate elections of 1930 occurred in the middle of Republican President Herbert Hoover's term. With the Great Depression beginning to take hold, Republican incumbents became unpopular, and Democrats picked up a net of eight seats, erasing the Republican gains from the previous election cycle. Republicans retained control of the U.S. Senate since Vice President Charles Curtis cast the tie-breaking vote. This was the first of four consecutive Senate elections in the Depression in which Democrats made enormous gains, achieving a cumulative pick-up of 34 seats.
