U.S. Reps. Rodney Davis and Mary Miller are running in the Republican primary for Illinois’ 15th Congressional District on June 28, 2022. This race is one of six incumbent-vs.-incumbent primaries occurring in 2022 as a result of congressional redistricting after the 2020 census.
Davis has represented Illinois’ 13th Congressional District since 2013. Miller has represented the 15th Congressional District since 2021. According to data from Daily Kos, 28% of the new 15th District’s population came from the old 13th District (represented by Davis), and 31% came from the old 15th District (represented by Miller). Illinois lost one congressional district following the 2020 census.
The Herald & Review‘s Brenden Moore wrote, “The race has been among the most contentious incumbent-versus-incumbent primaries in the country. … Davis and Miller have traded barbs over who is the true conservative candidate in the race.” According to OpenSecrets, the primary currently comes in second in total satellite spending out of all 2022 U.S. House races, with over $7.5 million spent as of June 15.
