1878–79 United States House of Representatives elections
The 1878–79 United States House of Representatives elections were held on various dates in various states between June 3, 1878 and September 3, 1879. Each state set its own date for its elections to the House of Representatives before or after the first session of the 46th United States Congress convened on March 18, 1879. Elections were held for all 293 seats, representing 38 states. This was the last election cycle that at least one state held its regular congressional election in an odd-numbered year. These elections occurred in the middle of President Rutherford B. Hayes's term. With a sour economy as the nation's pressing issue, both major parties lost seats to the new Greenback Party, which was established to promote the long-term use of paper money as a solution to stop enormous economic fluctuations. The Democratic Party remained the largest party, but lost its majority. However, it allied with several independent politicians and was able to remain in power. This was the fourth and last recorded House election where both major parties lost seats at the same time. Election summaries

Election dates 

In most states, the elections were held November 5, 1878. In 1845, Congress set a uniform nationwide date for choosing presidential electors. This Act of Congress did not affect election dates for Congress, which remained within the jurisdiction of state governments, but over time, the states moved their congressional elections to this date as well. In this cycle, there were still 7 states with earlier election dates, and 1 with a later election date:

 September 3, 1878: Vermont
 September 9, 1878: Maine
 October 7, 1878: Indiana

 Standard election date
 November 5, 1878

Pennsylvania

South Carolina 

South Carolina was rampant with voter fraud, particularly through the use of tissue ballots, thin ballots hidden in the normal ballot, typically 10 to 20 at a time. The almost statewide exclusion of Republicans as Commissioners of Elections, and the ensuing appointment of nearly all Democratic Managers of Elections, allowed to Democratic Managers to perpetrate this scheme. When the votes were counted and more votes than voters were found, the Managers removed and destroyed the Republican ballots resulting in the complete takeover of the state. |-
