U.S. Rep. Mary Miller defeated Rep. Rodney Davis in the Republican primary for Illinois’ 15th Congressional District on June 28, 2022. With 91% of precincts reporting, Miller had received 57.2% of the vote to Davis’ 42.8%.
This race was one of six U.S. House incumbent-vs.-incumbent primaries occurring in 2022 as a result of congressional redistricting.
The Herald & Review‘s Brenden Moore wrote that the race was “among the most contentious incumbent-versus-incumbent primaries in the country” and said the candidates “traded barbs over who [was] the true conservative candidate in the race.” As of election day, the primary had the second most satellite spending of all 2022 U.S. House races.
