Rep. Ken Calvert, R-Calif., is projected to win California's 40th Congressional District race, in a contest where gerrymandering pitted the two incumbents against each other. 

Calvert, the longest-serving Republican in California’s House delegation, ran against fellow GOP incumbent Rep. Young Kim. 

California voters had approved a Democrat-backed redistricting plan that combined portions of the two lawmakers' previous districts into one seat, Fox News reported. 

Kim had represented the area since 2018, and Calvert's district, which included much of Riverside County and Palm Springs, was redistributed. The race between the two lawmakers ultimately removed one Republican from the California delegation. 

Calvert is just one of three House Republicans in California to survive the midterms. He won with 53.6% of the vote against Kim's 46.4%, with 71% of the votes counted, according to the Associated Press.
