The 2002 United States Senate elections featured a series of fiercely contested elections that resulted in a victory for the Republican Party, which gained two seats and thus a narrow majority from the Democratic Party in the United States Senate. The Senate seats up for election, known as "class 2" Senate seats, were last up for regular election in 1996. The election was held on November 5, 2002, almost fourteen months after the September 11, 2001 attacks.
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 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 1934 occurred in the middle of Democratic President Franklin D. Roosevelt's first term.

President Harry S. Truman was first elected to the U.S. Senate in the 1934 election. 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.
