Speaker before election Paul Ryan Republican Elected Speaker Nancy Pelosi Democratic

In the 2018 midterm 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. The Democrats also won the popular vote by a margin of 8.6%, the largest margin on record for a party that previously held a minority in the House. Turnout was the highest for a midterm election in more than a century, with over half the electorate casting ballots.

Upon the opening of the 116th United States Congress, Pelosi was elected as Speaker of the House.[5] Incumbent Republican House Speaker Paul Ryan chose to retire in 2018 instead of seeking another term.[6] In November 2018, House Republicans elected Kevin McCarthy as House Minority Leader.[7]

Results summary and analysis

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.[8][9][10][11] Democrats won the popular vote by more than 9.7 million votes or 8.6%,[12] the largest midterm margin for any party[13] and the largest margin on record for a minority party.[14]

According to the Associated Press' statistical analysis, gerrymandering cost the Democrats an additional sixteen House seats from Republicans.[15]

4. This figure represents the difference between the number of Republicans seated when the 116th Congress convened in January 2019 (199) and the number of Republicans seated when the 115th Congress convened in January 2017 (241).
