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 1968 United States Senate elections were elections for the United States Senate. Held on November 5, the 34 seats of Class 3 were contested in regular elections.

This saw Republicans win a Senate seat in Florida for the first time since Reconstruction.
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 2023, this was the last time either party has had a two-thirds majority in the Senate, which allowed the Senate Democrats to override a veto, propose constitutional amendments, or convict and expel certain officials without any votes from Senate Republicans. However, internal divisions would have prevented the Democrats from having done so. The Senate election cycle 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.

This small change was just enough to give Democrats control of the chamber with the support of an Independent who agreed to caucus with them; he later officially joined the party in April 1955.
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 32 Senate seats of Class 1 were contested in regular elections, and three special elections were held to fill vacancies. The Republicans took control of the Senate by managing to make a net gain of two seats. However, Wayne Morse (R-OR) became an independent forcing Republicans to rely on Vice President Richard Nixon's tie-breaking vote, although Republicans maintained a 48–47–1 plurality. Throughout the next Congress, Republicans were able to restore their 49–46–1 majority. This was the third time, as well as second consecutive, in which a sitting Senate leader lost his seat.
The 1914 United States Senate elections were held on November 3, 1914. These were the first regularly scheduled elections held following the ratification of the Seventeenth Amendment to the United States Constitution in 1913, which required that all seats up for election be popularly elected, rather than chosen by their state legislatures. Thus, it was the first time that elections were generally scheduled on Election Day to coincide with the U.S. House elections. The 32 seats of Class 3 were contested in regular elections in 1914. Special elections were also held to fill vacancies. These elections occurred in the middle of Democratic President Woodrow Wilson's first term.

Potter in 1952. As of 2024, this is the last time that a Republican and a male candidate won the Class 1 Senate seat in Michigan.
