Rep. Mike Bost (R-Ill.), the incumbent in Illinois’ 12th District, has kept his seat in a tight GOP primary battle with Darren Bailey, a former state representative who previously lost the gubernatorial election to Democrat J.B. Pritzker.

The race was close. The Associated Press didn’t call it until 10:14 a.m. on March 20, on the morning after the primary.
