* Incumbent

Democrats are seeking to unseat Representative Mike Bost in a Southern Illinois district that supported former President Barack Obama in 2012 but swung heavily to President Trump in 2016. The district includes suburbs east of St. Louis, as well as farmland and coal mining towns to the south. Mr. Trump claimed credit for the reopening of a steel plant in Granite City, Ill., after imposing tariffs on imported steel.
