Byron Sigcho-Lopez is running against Patty Garcia (D, only Democrat on primary ballot); Mayra Macias (I).
The IL-04 race is unprecedented: Rep. Jesus "Chuy" Garcia announced retirement hours before the filing deadline, clearing the way for his chief of staff Patty Garcia to run unopposed in the Democratic primary. Sigcho-Lopez is running as an independent democratic socialist to challenge what he calls an "anti-democratic backroom deal."
As an independent, Sigcho-Lopez must collect 10,816 petition signatures by May 26 to appear on the November ballot. Has DSA endorsement. Given the district's heavy Democratic lean (Cook PVI D+36), the real battle is earning ballot access and name recognition against the party-backed candidate.
Key dates to watch: Primary on March 17, 2026 and General Election on November 3, 2026.
