Illinois's 18th congressional district


The 18th congressional district of Illinois covers central and western Illinois, including all of Jacksonville and Quincy and parts of Bloomington, Peoria, and Springfield. It is currently held by Republican Darin LaHood, who took office in September 2015 following a special election. Republican Aaron Schock had previously represented the district since January 2009, but resigned March 31, 2015. Special elections were called to select Schock's replacement, with a primary on July 7 and the general election on September 10, 2015. LaHood, son of Schock's predecessor Ray LaHood, won the special election and reelection in 2016 and 2018.
Abraham Lincoln served much of the area that now lies within the 18th district for a single term; it was numbered as the 7th district at the time. It also contains most of the territory that was represented by future United States Senate Minority Leader Everett Dirksen and longtime House Minority Leader Bob Michel.
From 1949 to 2015, the district was represented by someone who either attended or graduated from Bradley University.
