History

The area of the district was originally represented by one of Abraham Lincoln's closest allies, Elihu B. Washburne (R-Waukegan). The district was created in 1982 redistricting out of districts represented by John Porter (R-Wilmette) and Robert McClory (R-Lake Bluff). On the retirement of McClory, the district was represented by Porter after winning the elections of 1982, 1984, 1986, 1988, 1990, 1992, 1994, 1996, and 1998. Following Porter's retirement, 11 Republicans and two Democrats ran to succeed him. Eventually 9 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 Representative Lauren Beth Gash (D-Highland Park) by 2% in the 2000 general election. Kirk remained in Congress until he decided to run for the United States Senate in the 2010 election. He was succeeded by Republican Robert Dold.
