The Winner

If you live in Illinois's 10th U.S. House District, you will continue to be represented in Congress by Rep. Brad Schneider (D-IL), who has been declared the winner of the 2026 congressional race, according to the Associated Press. ​

Schneider took about 70.0 percent of the vote to about 30.0 percent for Republican Carl Lambrecht, a margin of about 40 points, according to the state's official results as of Nov. 10.

That works out to about 163,526 votes for Schneider and about 70,112 for Lambrecht, a gap of about 93,414 votes. The winner is based on the Associated Press call; the vote figures are preliminary, and totals may change until the state certifies them. The seat stays in Democratic hands.

The Race

Lambrecht reached the general election ballot by winning the March 17 Republican primary, where he was the only candidate. Inside Elections rated the seat "Solid Democrat" before the election.

Illinois's 10th District has about 753,700 residents, according to Geographies data for the district. Median household income is about $107,400 and median age is about 39.6.

About 47.0 percent of adults hold a bachelor's degree or higher, the unemployment rate is about 5.2 percent, and about 8.5 percent of residents live below the poverty line. Residents are about 61.8 percent white, 24.7 percent Hispanic, 8.3 percent Asian, and 6.4 percent Black.

The district covers Lake County and part of Cook County, according to the Illinois Secretary of State.

What's Next

Schneider, of Highland Park, Illinois, is set to take office on Jan. 3, 2027. He called for changes to House rules in 2027, including limits on members' participation in prediction markets, limited proxy voting for pregnancy and parental leave, bipartisan co-lead sponsors on bills, and coordinated committee schedules, according to the New Democrat Coalition.

The group reported his proposals after his testimony at a House Rules Committee hearing on Sept. 2.
