Race summary
The 13th District is the creative centerpiece of Illinois’ gerrymander, snaking west between the liberal cores of Champaign, Decatur and Springfield before settling in the St. Louis suburbs. Republicans flirted with a challenge to Rep. Nikki Budzinski in 2022, but she’s since become a top overperformer and won her last race by 16 points (Kamala Harris carried the district by 11).Key Dates
