# 1942 United States House of Representatives elections

The 1942 United States House of Representatives elections were elections for the United States House of Representatives to elect members to serve in the 78th United States Congress. They were held for the most part on November 3, 1942, while Maine held theirs on September 14. This was the first election after the congressional reapportionment based on the 1940 census, and was held in the middle of President Franklin D. Roosevelt's third term. With involvement in World War II, it was the first wartime election in the United States since 1918.
Roosevelt's Democratic Party lost 45 seats to the Republican Party, retaining only a slender majority even though they lost the popular vote by over 1 million votes (3.9%). The election was the second of four times in the 20th century in which either party won the House majority without winning the popular vote, with the other three instances occurring in 1914, 1952, and 1996; Democrats won the House majority without winning the popular vote in the former election, while Republicans did so in the latter two.
This was the most successful congressional election for Republicans since 1930, and the first time since that election cycle that the House GOP actually won the popular vote. The main factor that led to the Republican gains during this election cycle was dissatisfaction with the conduct of America's war effort in World War II.
As of 2024, this was the last time the House of Representatives was made up of five parties. This was also the smallest House majority that the Democrats had up until the 2020 elections. Voter turnout was historically low for the time, which was attributed to the absence of military men and the apathy of workers at war production plants, many of whom had failed to re-register to vote in their new communities or become accustomed to local candidates.

## Indiana

Indiana was redrawn from 12 districts to 11 after reapportionment; most of the districts underwent minor boundary changes, and the old 11th district was divided up, distributing Madison County to the 5th, Hancock County to the 10th, and consolidating the parts of Marion County in the old 11th and Indianapolis-based 12th into a new 11th. This forced incumbents William Larrabee and Raymond S. Springer to run against each other in a district drawn mainly from Springer's old district.
