1970 United States House of Representatives elections
The 1970 United States House of Representatives elections was an election for the United States House of Representatives held on November 3, 1970, to elect members to serve in the 92nd United States Congress. They occurred in the middle of Richard M. Nixon's first term as president. His party, the Republican Party, lost a net of 12 seats to the Democratic Party, which thereby increased its majority in the House. Many viewed the results of the 1970 election as an indication of public fatigue over the ongoing Vietnam War as well as the fallout from the Kent State Massacre. This was the first House election in which all 50 states used a single-member-district system to elect representatives instead of using at-large congressional districts. Overall results
