The 4th Congressional District of Illinois includes part of Cook County, and has been represented by Democrat Luis Gutierrez since January 1993.
It was featured by The Economist as one of the most strangely drawn and gerrymandered congressional districts in the country. It was created to contain two majority Hispanic parts of Chicago.
This district covers two strips running east-west across the city of Chicago, Illinois on the west side continuing into smaller portion of some suburban areas in Cook County, surrounding Illinois' 7th congressional district. The northern portion is largely Puerto Rican, while the southern portion is heavily Mexican. The two sections are on opposite sides of the city and are only connected by a piece of Interstate 294 to the west; the highway is in the district while the surrounding areas are not. It is the smallest congressional district in area outside of New York City and San Francisco. George W. Bush received 21% of the vote in this district in 2004. The district has a Cook Partisan Voting Index score of D +31.
