A total of 23 seats in Congress flipped political parties during the 2022 midterm elections, data shows.
Of the 23 seats that switched political parties, 16 seats flipped from Democrat to Republican and seven flipped from Republican to Democrat.
The House of Representatives is a 435-seat chamber. A party needs to hold 218 seats to claim a majority. Ahead of the 2022 midterms, Democrats held 220 seats and Republicans held 212 seats. Nine incumbents—six Democrats and three Republicans—lost their reelection bids on Nov. 8. Three seats were vacant.
Of the three vacant seats, two were previously held by Democrats and one was held by a Republican:
- Florida’s 13th District: Democrat Charlie Crist resigned on Aug. 31 with no special election held.
- Florida’s 23rd District: Democrat Ted Deutch resigned on Sept. 30 with no special election held.
- Indiana’s 2nd District: Republican Jackie Walorski died on Aug. 3. A special election was held Nov. 8.
The 2022 midterms were the first elections to take place following congressional apportionment and redistricting after the 2020 census. As a result of apportionment, six states—Texas, Colorado, Florida, Montana, North Carolina, and Oregon—gained districts. Seven states—California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia—lost districts.
Starting in January, when the new members are sworn in, Republicans will control 221 House seats, leaving Democrats with 212 seats.
Of the 23 congressional seats that switched political parties, 16 seats flipped from Democrat to Republican and seven flipped from Republican to Democrat.
Democrat to Republican
- District 2: Republican Eli Crane defeated three-term Democrat Rep. Tom O’Halleran. The election filled the seat held by Democrat Ann Kirkpatrick, who first assumed office in 2019. Kirkpatrick announced on March 12, 2021, that she would seek reelection.
- District 13: Republican Anna Paulina Luna defeated Democrat Eric Lynn, 53 percent to 45 percent. The newly redrawn district had been represented by Democrat Charlie Crist, who resigned his office to launch an unsuccessful gubernatorial challenge against Republican Gov. Ron DeSantis.

Iowa will send four Republicans to the House of Representatives for the first time since 2004, when the state had five representatives. Iowa’s House delegation has not been singularly Republican since 1994.
- District 10: In a redrawn congressional district in the Detroit suburbs, Republican John James defeated Democrat Carl Marlinga by a narrow margin of 48.6 percent to 48.4 percent.

- District 3: New York Republican George Devolder-Santos defeated Democrat Robert Zimmerman by a margin of nearly 8.4 points—54.2 percent to 45.8 percent—flipping the district to red for the first time since 2010. Zimmerman sought the Long Island seat after Democrat Rep. Tom Suozzi, who held the district since 2016, vacated his seat to launch an unsuccessful gubernatorial bid.

- District 5: Republican Andy Ogles defeated Democrat Heidi Campbell 56.3 percent to 42.6 percent. Ogles will replace retiring Democrat Jim Cooper, who decided not to seek reelection following redistricting that shifted the district from solid blue to “likely” red.
- District 2: Republican Jennifer Kiggans unseated incumbent Democrat Rep. Elaine Luria by a margin of 52 percent to 47.9 percent. Luria had held the seat since 2018.

Republican to Democrat
- At-Large District: Incumbent Democrat Rep. Mary Peltola defeated Republicans Sarah Palin and Nick Begich and Libertarian candidate Chris Bye. Peltola, Begich, Palin, and Republican Tara Sweeney advanced from the Aug. 16 top-four primary. Sweeney withdrew from the race, leaving Bye, the fifth-place finisher, to advance. The seat was left vacant by the death of Republican Rep. Don Young in March. Young had held the office since 1973.
- District 13: Democrat Nikki Budzinski defeated Republican Regan Deering by a margin of 54.7 percent to 45.3 percent. The seat had been held by Republican Rodney Davis, who lost the Republican primary on June 28 and had held the seat since 2013.

- District 2: Democrat Gabriel Vasquez defeated freshman incumbent Republican Rep. Yvette Herrell by a margin of about 1,300 votes. Vasquez’s win once again gives New Mexico an all-Democrat congressional delegation.
