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 1956 United States Senate elections were elections for the United States Senate that coincided with the re-election of President Dwight D. Eisenhower. Although the Democrats gained two seats in regular elections, the Republicans gained back two seats in special elections, leaving the party balance of the chamber remained unchanged.
The 1950 United States Senate elections occurred in the middle of Harry S. Truman's second term as President. 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.
The 1948 United States Senate elections were elections which coincided with the election of Democratic President Harry S. Truman for a full term. Truman had campaigned against an "obstructionist" Congress that had blocked many of his initiatives, and in addition the U.S. economy recovered from the postwar recession of 1946–47 by election day. Thus Truman was rewarded with a Democratic gain of nine seats in the Senate, enough to give them control of the chamber.
The 1946 United States Senate elections were held November 5, 1946, in the middle of Democratic President Harry S. Truman's first term.
The United States Senate elections of 1938 occurred in the middle of Franklin D. Roosevelt's second term. This occurred six years after the Democratic landslide in the 1932 election, and so the opposition Republicans gained seven seats from the Democrats. However, the Democrats retained a commanding lead over the Republicans with more than two-thirds of the chamber.
Although the 17th Amendment was not passed until 1913, some states elected their Senators directly before its passage. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.
