Daniel Biss wins in Illinois' 9th District Democratic primary

Daniel Biss defeated a crowded field in Tuesday's Democratic primary to represent Illinois' 9th District.

• Biss faces Republican John Elleson in November.

Flashback: U.S. Rep. Jan Schakowsky's retirement announcement last year opened the seat for the first time in more than 25 years, prompting 15 Democrats and four Republicans to enter the race.

Zoom in: Biss has been mayor of Evanston, the northern suburb that's home to Northwestern University, since 2021 and has also served as both a state Senator and state Representative.

• Schakowsky endorsed Biss, along with U.S. Senators Tammy Duckworth (D-Ill.) and Elizabeth Warren (D-Mass.).
• Biss' calls to abolish ICE became more fervent after a standoff in December with Border Patrol Commander Gregory Bovino, as immigration officials made arrests in Evanston and nearby suburbs.

State of play: The district includes Rogers Park — one of Chicago's most diverse neighborhoods — and the affluent North Shore suburbs, home to what have long been known as "lakefront liberal" voters.
