Illinois’ 10th Congressional District House Race 2026

With Election Day a week away, Illinois Democrats are campaigning beyond state lines to aid party allies nationally. Rep. Raja Krishnamoorthi backed Texas Railroad Commissioner candidate Jon Rosenthal; Sen. Tammy Duckworth campaigned for Sherrod Brown in Ohio; Rahm Emanuel canvassed in New Hampshire; and Rep. Danny Davis and successor nominee La Shawn Ford campaigned for Wisconsin gubernatorial candidate David Crowley. Gov. JB Pritzker is focused on his own reelection, holding a large cash advantage and backing fellow Democrats financially.

Big money is also flowing into Illinois races, including Chicago school board contests, with GOP megadonors Dick and Elizabeth Uihlein and wealthy Democratic-aligned groups both spending heavily to shape outcomes from Springfield to Chicago.

Illinois Democrats are split on strategy ahead of potential midterm gains that could hand their party control of the House and possibly the Senate. Some, like Lt. Gov. Juliana Stratton, who is running for Senate, favor confrontation, including refusing to confirm Trump nominees or fund ICE and potentially ending the filibuster. Others, including Sen. Tammy Duckworth and Rep. Bill Foster, favor combining aggressive oversight of Trump officials and businesses with legislative wins, while downplaying quick impeachment. Republicans, including Speaker Mike Johnson and Trump himself, warn that a Democratic majority would mean relentless investigations and a renewed impeachment push.

The debate reflects broader uncertainty over Democratic strategy and control of Congress following the November midterms, a key variable for prediction markets tracking the 2026 elections and any renewed impeachment proceedings.

Federal prosecutors have charged Matthew Unglesbee, 37, of Quincy, Illinois, with mailing threatening communications and perpetrating a hoax after at least four envelopes containing a white powder, postmarked in Springfield on Oct. 19, were sent to Illinois congressional offices, including Reps. Brad Schneider, Mike Quigley and Jan Schakowsky, with a fifth unmailed envelope addressed to a Washington, D.C. office found during a search. Notes read "HA HA" and "HAH enjoy the gift." Testing found the substance harmless; Unglesbee admitted using salt because it resembled anthrax, telling agents it was a joke inspired by similar nationwide mailings. The FBI arrested him at his mother's Quincy home; he has a prior criminal history including threatening a public official.

Democrats have added Wisconsin's 1st Congressional District, held by Republican Rep. Bryan Steil since 2019, to the DCCC's "red to blue" target list, boosting resources for challenger Mitchell Berman, a nurse and first-time candidate. Democrats hope voter anger over Trump's approval rating, healthcare costs, gas prices and tariffs could turn a modest "blue wave" into a bigger upset, though officials in both parties consider it a long shot given Steil's name recognition and fundraising edge.

Steil and allied groups have outspent Berman roughly 2-1, entering August with $6.3 million cash on hand versus about $152,000 for Berman. Nationally, Trump-aligned groups No Going Back PAC and Safety and Affordability PAC have spent more than $84 million on House ads since September, with 96% concentrated in districts Trump carried in 2024 — a sign Republicans are playing defense but retain a financial cushion. Steil, seen as a possible 2028 Senate contender, has won his prior four races by at least 9 points. The district, anchored by Racine, Kenosha and Janesville, leans Republican but has grown more competitive under redrawn maps.

Former U.S. Rep. Melissa Bean, a centrist Democrat, is seeking a political comeback in Illinois' 8th Congressional District, facing Republican newcomer Jennifer Davis in the Nov. 3 general election. The seat is open after Democratic Rep. Raja Krishnamoorthi, who has endorsed Bean, left to run unsuccessfully for U.S. Senate. An independent write-in candidate, Christopher Krumpac, is also running.

The district, which stretches from the northwest Chicago suburbs to Elgin and the Fox River Valley, leans solidly Democratic. Bean, who first won the seat in 2004 and served until 2011, has outraised Davis, aided in part by a super PAC tied to AIPAC that drew progressive criticism during the primary. Davis, a tech entrepreneur making her first run for office, has loaned her own campaign $1 million to stay competitive.

The candidates diverge sharply on abortion, immigration, and Trump-era policies, with Bean casting the race as a check on the administration and Davis positioning herself as a political outsider focused on small business and economic concerns.

Project 50, a political group founded by Illinois abortion-rights veterans including former state Sen. Heather Steans and ex-HHS Secretary Kathleen Sebelius, is working to replicate Illinois' decades-old shift toward abortion access by targeting state legislative races in conservative states with bans or heavy restrictions. After early setbacks in Arizona, the group refocused on culturally conservative states in 2023, winning three races in its first three years and four more in 2025, including in Virginia. It has raised over $3.7 million from donors such as Michael Bloomberg and Gov. JB Pritzker. Organizers say the strategy targets voters uneasy with total abortion bans, not broad support for unrestricted access. Abortion-rights opponents call its electoral impact limited so far.

Illinois voters head to the polls Nov. 3 to fill an open U.S. Senate seat and decide contests for governor, attorney general, secretary of state, comptroller and treasurer. Lt. Gov. Juliana Stratton faces Republican Don Tracy for the Senate seat being vacated by Dick Durbin. Gov. J.B. Pritzker, running with new lieutenant governor pick Christian Mitchell, seeks a third term in a rematch against Darren Bailey, who has Donald Trump's endorsement and running mate Aaron Del Mar.

Incumbent Attorney General Kwame Raoul faces Republican Bob Fioretti, while Secretary of State Alexi Giannoulias, now also running for Chicago mayor, is challenged by Republican Diane Harris. With Comptroller Susana Mendoza not seeking re-election amid her own mayoral bid, Democrat Margaret Croke and Republican Bryan Drew are competing for that office. Treasurer Mike Frerichs seeks re-election against Republican Max Solomon. The races will shape state policy on taxes, spending oversight, abortion access and Illinois' relationship with the Trump administration, with early and mail voting available ahead of Election Day.

A House Judiciary Committee interim staff report, released by Chairman Jim Jordan (R-OH) and obtained by the Washington Examiner, alleges that Illinois and Chicago authorities released more than 500 immigrants from custody rather than honor federal ICE detainers. The report says some of those released were later accused or convicted of crimes including murder, domestic violence, and robbery.

Republicans on the committee attribute the releases to Illinois's sanctuary policies, which restrict state and local cooperation with federal immigration enforcement. The findings add to an ongoing partisan fight over sanctuary jurisdictions, with Illinois Gov. J.B. Pritzker and Chicago officials defending their policies against criticism from the Trump administration and congressional Republicans. The report is likely to fuel further legislative and legal efforts targeting sanctuary city laws and could influence prediction markets tracking federal-state immigration enforcement disputes and potential policy changes in Illinois.
