Incumbent Republican Mike Bost faces Democrat Julie Fortier in the November 3, 2026, general election for Illinois's 12th congressional district. The seat carries a Cook Partisan Voting Index of R+22 and receives Solid Republican or Safe Republican ratings from nonpartisan forecasters. Bost secured renomination without opposition in the March 17 primary and holds a substantial fundraising lead. The district's consistent Republican performance, including Bost's 74 percent share in 2024, underpins trader consensus favoring the Republican nominee. A late scandal, significant health event, or unusually strong Democratic national environment could narrow the margin, though structural factors limit the scope for an upset.
