The 1948 United States presidential election was the 41st quadrennial presidential election. It was held on Tuesday, November 2, 1948. In one of the greatest election upsets in American history, incumbent President Harry S. Truman, the Democratic nominee, defeated heavily-favored Republican Governor of New York Thomas E. Dewey and other third-party candidates, becoming the third president to succeed to the presidency upon his predecessor’s death and be elected to a full term.
The 1948 United States Senate elections were elections which coincided with the election of Democratic President Harry S. Truman for a full term. The 32 seats of Class 2 were contested in regular elections, and one special election was held to fill a vacancy. 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 1946–1947 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. This was the last time until 2020 that Democrats flipped a chamber of Congress in a presidential election cycle.
The 1948 United States House of Representatives elections were elections for the United States House of Representatives to elect members to serve in the 81st United States Congress. They were held for the most part on November 2, 1948, while Maine held theirs on September 13. These elections coincided with President Harry S. Truman's election to a full term. Truman had campaigned against a "do-nothing"' Republican Party Congress that had opposed his initiatives and was seen as counterproductive. The Democratic Party regained control of both the House and Senate in this election. For Democrats, this was their largest gain since 1932. These were the last elections until 1980 when a member of a political party other than the Democrats, Republicans, or an independent had one or more seats in the chamber. As of 2023, this is the last time the Democrats gained more than 50 seats in an election.

Sims, Jr. The seat remained with the Democrats along with the open seat in the 3rd congressional district and the composition of the state delegation remained solely Democratic.
