Mike Bost (R) defeated Brendan Kelly (D) and Randy Auxier (G) in the 2018 general election for Illinois' 12th Congressional District.
All 435 seats in the U.S. House of Representatives were up for election in 2018. The Democratic Party gained a net total of 40 seats, winning control of the chamber. This race was identified as a 2018 battleground that might have affected partisan control of the U.S. House in the 116th Congress. 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.
Prior to Bost's election in 2014, the seat had been held by Democrats since 1993. Bost was re-elected in 2016 with a 14 point margin of victory over his Democratic opponent. The 12th District was targeted by the Democratic Congressional Campaign Committee (DCCC) in 2018.
