California, U.S. House, District 8

Incumbent Paul Cook (R) defeated Tim Donnelly (R) in the 2018 general election for California's 8th Congressional District.

Cook was first elected to represent the district in 2012 and was last re-elected in 2016 by a margin of 25 percentage points, facing a Democratic opponent. The 2018 general election was Cook's first general election against a Republican opponent and the only U.S. House election in 2018 to feature two Republican candidates in the general election.

Cook was endorsed by President Donald Trump (R), the National Border Patrol Council, and the National Rifle Association. Donnelly, a former Minuteman leader, was endorsed by Sen. Rand Paul (R) and Turning Point USA founder Charlie Kirk.

All 435 seats in the U.S. House of Representatives were up for election in 2018. Heading into the election, the Republican Party was in the majority holding 235 seats to Democrats' 193 seats, with seven vacant seats. Democrats needed to win 23 GOP-held seats in 2018 to win control of the House. From 1918 to 2016, the president’s party lost an average of 29 seats in midterm elections.
