The U.S. House election, 1970 was an election for the United States House of Representatives held on November 3, 1970, in the middle of President Richard M. Nixon's first term. The President's Republican Party lost seats, in this case a net of 12, to the Democratic Party, which thus increased modestly its majority in the House. Many viewed the results as the American public showing fatigue over the ongoing Vietnam War. This was also the first House election when all 50 states were using the same regional single-member district system to elect Representatives instead of using at-large congressional districts.
