2018 United States House of Representatives elections

The 2018 United States House of Representatives elections were held on November 6, 2018, as part of the 2018 midterm elections during President Donald Trump's first term, with early voting taking place in some states in the weeks preceding that date. Voters chose representatives from all 435 congressional districts across each of the 50 U.S. states to serve in the 116th United States Congress. Non-voting delegates from the District of Columbia and four of the five inhabited U.S. territories were also elected. On Election Day, Republicans had held a House majority since January 2011.

Speaker before election Paul Ryan Republican Elected Speaker Nancy Pelosi Democratic

In the 2018 elections, the Democrats, led by Nancy Pelosi, won control of the House. The Democrats gained a net total of 41 seats from the total number of seats they had won in the 2016 elections. The 41-seat gain was the Democrats' largest gain of House seats since the post-Watergate 1974 elections, when they picked up 49 seats. This was the first time since 1954 that Democrats flipped a chamber of Congress in a Republican president's first midterm. Democrats also won the popular vote by an 8.6% margin, the largest margin of victory for any party during a midterm election since 1986.

Upon the opening of the 116th Congress, Pelosi was elected as Speaker of the House. Incumbent Republican House Speaker Paul Ryan chose not to run for another term. In November 2018, House Republicans elected Kevin McCarthy as House Minority Leader.

The House Republicans' passage of the widely unpopular American Health Care Act of 2017 to repeal the Affordable Care Act, as well as opposition to Trump's policies, his low approval ratings, and questions about his personal stamina for office, are credited for the Democratic takeover of the House.

This marks the last time Democrats won any House seats in Oklahoma and Utah; the last time they won a majority of seats in Iowa and Minnesota; and the last time they won every seat based in New York City, Los Angeles County, and Orange County, California. As of 2025, this is the last time any party won at least 230 House seats.

Results summary and analysis

Federal

The Democratic Party won control of the House of Representatives in the 2018 midterm elections. The Democrats gained a net total of 41 seats from the total number of seats they had won in the 2016 elections. This was their largest gain of House seats in an election since the 1974 elections, when the Democrats gained 49 House seats. Democrats won the popular vote by more than 9.7 million votes, or 8.6%, the largest midterm margin for any party and the largest margin on record for a minority party.

According to the Associated Press' statistical analysis, gerrymandering cost the Democrats an additional sixteen House seats from Republicans.

Voter turnout in this election was 50.3%, the highest turnout in a U.S. midterm election since 1914.
