Democrat Lt. Gov. Juliana Stratton's 91.5% implied probability in the Illinois U.S. Senate race reflects the state's entrenched Democratic lean, where Chicago and suburban Cook County deliver overwhelming margins that routinely overpower downstate Republican strongholds, as seen in recent cycles like Tammy Duckworth's double-digit 2022 victory. Following the March 17 primaries, Stratton consolidated support with Gov. JB Pritzker's endorsement after topping a crowded Democratic field at 40%, while GOP nominee Don Tracy, former state party chair, advances in a low-profile contest. Absent public general election polls, traders price in historical base rates favoring Democrats by 10-15 points in open-seat scenarios. Late challenges could arise from a national Republican midterm wave, Stratton scandal, or exceptional GOP turnout, though structural barriers remain high ahead of the November 3 vote.

A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date.
Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party.
