The 2000 United States Senate elections were held on November 7, 2000. The elections coincided with other federal and state elections, including the presidential election which was won by Republican George W. Bush. These elections took place six years after Republicans had won a net gain of eight seats in Senate Class 1. Despite George W. Bush's victory in the presidential election, the GOP lost 4 senate seats, the most a winning president's party has lost since the passage of the 17th amendment. This election marked the first election year since 1990 where Democrats made net gains in the Senate. Democrats defeated incumbent Republicans in Delaware, Michigan, Minnesota, Missouri, and Washington, and they won an open seat in Florida. In Missouri, the winner was elected posthumously. The Republicans defeated a Democratic incumbent in Virginia, and won an open seat in Nevada. Additionally, a Republican in Georgia died earlier in the year and a Democrat was appointed to replace him, who then went on to win the special election.
The 1994 United States Senate elections were held November 8, 1994, with the 33 seats of Class 1 contested in regular elections. Special elections were also held to fill vacancies. The Republican Party took control of the Senate from the Democrats. Like for most other midterm elections, the opposition, this time being the Republicans, held the traditional advantage. The congressional Republicans campaigned against the early presidency of Bill Clinton, including his unsuccessful health care plan. Democrats held a 56-44 majority, after having lost a seat in Texas in a 1993 special election.
The 1982 United States Senate elections were held on November 2, 1982. They were elections for the United States Senate following Republican gains in 1980. The 33 Senate seats of Class 1 were up for election in 1982. A total of four seats changed hands between parties, with Democrats winning seats in New Jersey and New Mexico, and Republicans taking seats in Nevada and the seat of the lone independent, Senator Harry Byrd Jr., in Virginia. Democrats made a net gain of one seat bringing them to 46 seats, while Republicans stayed at 54 seats for a majority. However, the Democratic gain in New Jersey replaced a Republican that had been appointed earlier in the year.
The 1980 United States Senate elections were held on November 4, coinciding with Ronald Reagan's victory in the presidential election. The 34 Senate seats of Class 3 were contested in regular elections. Reagan's large margin of victory over incumbent Jimmy Carter gave a huge boost to Republican Senate candidates, allowing them to flip 12 Democratic seats and win control of the chamber for the first time since the end of the 83rd Congress in January 1955.
The 2008 United States Senate elections were held on November 4, 2008, with 35 of the 100 seats in the Senate being contested. Thirty-three seats were up for regular elections; the winners were eligible to serve six-year terms from January 3, 2009, to January 3, 2015, as members of Class 2. There were also two special elections, the winners of those seats would finish the terms that ended on January 3, 2013. The presidential election, which was won by Democrat Barack Obama, elections for all House of Representatives seats; elections for several gubernatorial elections; and many state and local elections occurred on the same date.

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 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 1960 United States Senate elections coincided with the election of John F. Kennedy as president on November 8, 1960. The 33 seats of Class 2 were contested in regular elections. A special election was also held on June 28, 1960, for a mid-term vacancy in North Dakota where Democrats flipped a seat to expand their majority to 66–34. As Majority Leader Lyndon Johnson was elected Vice President, Mike Mansfield became the new majority leader.
Clifford Philip Case Jr., was an American lawyer and politician. For over 30 years, Case represented the state of New Jersey as a member of the Republican Party both in the U.S. House of Representatives (1945–1953) and the U.S. Senate (1955–1979). Throughout his career in the House and Senate, Case proved to be one of the most left-leaning members of the Republican Party, supporting labor union rights, civil rights for African-Americans, and social welfare programs, which put him at odds with the most right-leaning members of his party.
