Daniel Biss's commanding 100% trader consensus in the Illinois 9th Congressional District Democratic primary stems from his decisive victory on March 19, 2024, capturing 53% of the vote against Kate Abughazaleh's 22% and Laura Fine's 16%, with incumbent Jan Schakowsky retiring after 14 terms. Pre-election polls consistently showed Biss leading, bolstered by strong fundraising—over $3 million raised—and key endorsements from labor unions and progressive groups. This skin-in-the-game pricing reflects certified results from the Illinois State Board of Elections, with negligible volume on challengers. Realistic challenges, such as a recount or legal dispute, appear improbable given the 30+ point margin, though final certification could theoretically shift odds if anomalies emerge.
