The 1980 United States Senate elections coincided with Ronald Reagan's victory in the presidential election. Reagan's large margin of victory over incumbent Jimmy Carter pulled in many Democratic voters and gave a huge boost to Republican Senate candidates.
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 1974 United States Senate elections were held in the wake of the Watergate scandal, Richard M. Nixon's resignation from the presidency, and Gerald Ford's subsequent pardon of Nixon. Economic issues, specifically inflation and stagnation, were also a factor that contributed to Republican losses. Democrats made a net gain of three seats from the Republicans. Following the 1974 elections, the Democratic caucus controlled 60 seats and the Republican caucus controlled 39 seats.

The Senate election coincided with Democratic gains in the House in the same year.

As with most 20th-century second-term mid-terms, the party out of the Presidency made significant gains. The Republican opposition made a net gain of five seats, taking advantage of the Democratic administration's declining popularity during the Cold War and the aftermath of the Recession of 1949. The Democrats held a narrow 49 to 47 seat majority after the election. This became the first time since 1932 that the Senate Majority Leader lost his seat and the only instance where the majority leader lost his seat while his party retained the majority.

Truman and popular Wisconsin Senator Joseph McCarthy endorsing his campaign.
