Illinois's 9th congressional district

The 9th congressional district of Illinois covers parts of Cook County, as of the 2011 redistricting which followed the 2010 census. All or parts of Chicago, Des Plaines, Evanston, Glenview, Lincolnwood, Morton Grove, Mount Prospect, Niles, Park Ridge, Prospect Heights, Skokie, Wilmette and Winnetka and Arlington Heights are included. It is anchored in Chicago's North Side along Lake Michigan, and covers many of Chicago's northern suburbs. Democrat Jan Schakowsky has represented the district since January 1999.

The district is one of the most reliably Democratic districts in Chicago, and in all of Illinois. It has been in Democratic hands without interruption since 1949, and for all but six years since 1935. Only three people have held the district since 1949--Sidney Yates, Edward Finnegan, and Schakowsky. Yates gave up the seat in 1962 to run for United States Senate. When he lost, Chicago machine officials persuaded Finnegan, who had succeeded Yates after his former district was merged with the 9th, to hand the seat back to Yates. Schakowsky won the seat in 1998 after Yates retired.
