The10thcongressional district of Illinois lies in the northeast corner of the state and mostly comprises northern suburbs ofChicago. It was created after the1860 census. The district is currently represented byDemocratBrad Schneider.

The area of the district was originally represented by one ofAbraham Lincoln's closest allies,Elihu B. Washburne (R-Waukegan). The district was created in 1982 redistricting out of districts represented byJohn Porter (R-Wilmette) andRobert McClory (R-Lake Bluff). On the retirement of McClory, the district was represented by Porter after winning the elections of1982,1984,1986,1988,1990,1992,1994,1996, and1998. Following Porter's retirement, 11 Republicans and two Democrats ran to succeed him. Eventually nine Republicans and one Democrat stood for election in the primary of March 2000. John Porter's former Chief of Staff, Mark Kirk, won the Republican primary over number two rival Shaun Donnely. Kirk then defeated State RepresentativeLauren Beth Gash (D-Highland Park) by 2% in the2000 general election. Kirk remained in Congress until he decided to run for theUnited States Senate in the 2010 election. He was succeeded byRepublicanRobert Dold.

The 10th is home to several Fortune 500 companies, including, but not limited to:CDW,Walgreens,Underwriters Laboratories,Caterpillar, Inc.,Baxter Healthcare,AbbVie,Allstate Insurance, andMondelez International.
