Evanston Mayor Daniel Biss's victory in the March 17 Democratic primary for Illinois' 9th Congressional District—capturing nearly 30% in a crowded 16-candidate field, with outgoing incumbent Jan Schakowsky's endorsement—has solidified trader consensus at 93.5% for the Democratic Party in this D+19 Cook PVI stronghold. The district's North Chicago suburbs have delivered Democratic House wins by 68-71% in recent cycles, dwarfing low-turnout Republican primary results where John Elleson advanced amid just 12,000 votes. Ratings from Cook Political Report and Sabato's Crystal Ball deem it Solid or Safe Democratic. Upsets would require a major Biss scandal, personal crisis, or extraordinary national Republican midterm surge to overcome entrenched partisan math ahead of the November 3 general election.
