Illinois’s 9th congressional district remains a strongly Democratic seat following longtime incumbent Jan Schakowsky’s retirement, with the March 2026 primary producing Evanston Mayor Daniel Biss as the nominee against Republican John Elleson. The district’s partisan lean, reflected in consistent Democratic performance in prior cycles and a sizable partisan voting index advantage, anchors trader pricing near 93-94% for the Democratic nominee. Biss consolidated support after defeating a crowded field that included state Sen. Laura Fine and content creator Kat Abughazaleh, while the Republican side has drawn limited visibility or fundraising. A late scandal, national Republican surge, or unusually depressed Democratic turnout could narrow the margin, though structural factors and historical results make such shifts improbable before the November 3 general election.
