context_page_description: Elections were held on November 2, 2010, to determine Illinois's 19 members of the United States House of Representatives. Representatives were elected for two-year terms to serve in the 112th United States Congress from January 3, 2011, until January 3, 2013. Primary elections were held on February 2, 2010.
  Of the 19 elections, the 10th, 11th, 14th and 17th districts were rated as competitive by CQ Politics and The Rothenberg Political Report; while the 8th, 10th, 11th, 14th and 17th districts were rated as competitive by The Cook Political Report and Sabato's Crystal Ball. Of Illinois's nineteen U.S. Representatives, fourteen were re-elected. Republican Mark Kirk of the 10th district did not seek re-election in order to run for the U.S. Senate, while Democrats Melissa Bean of the 8th district, Debbie Halvorson of the 11th district, Bill Foster of the 14th district and Phil Hare of the 17th district were defeated in the general election.
  In total, eleven Republicans and eight Democrats were elected.

The district's population was 71 percent white, 15 percent Hispanic, 8 percent Asian and 5 percent black (see Race and ethnicity in the United States Census); 90 percent were high school graduates and 51 percent had received a bachelor's degree or higher. Its median income was $85,468. In the 2008 presidential election the district gave 61 percent of its vote to Democratic nominee Barack Obama and 38 percent to Republican nominee John McCain. In 2010 the district had a Cook Partisan Voting Index of D+6.
  Republican Mark Kirk, who took office in 2001, was the incumbent. Kirk was re-elected in 2008 with 53 percent of the vote. In 2010 Kirk ran for the U.S. Senate rather than seeking re-election. The candidates in the general election were Republican nominee Bob Dold, who at the time ran his family business; and Democratic nominee Dan Seals, a social worker.

In a poll of the Democratic primary by Anzalone Liszt Research for Seals's campaign, the results of which were published in August 2009, 63 percent of respondents supported Seals, while 8 percent favored Hamos and 2 percent chose Richardson. Michael Bond, a member of the Illinois Senate; and Milton Sumption, a businessman ended their respective campaigns for the Democratic nomination in December 2009. Susan Garrett, also a Democratic member of the state Senate, said in the same month that she had decided not to run.  Richard B. Mayers, an unemployed admitted anti-Semite, sought the Green Party nomination but was removed from the ballot in November 2009 after failing to submit enough valid signatures.
