Bailey Launches 2026 Rematch Against Pritzker, Taps Cook County GOP Chair Aaron Del Mar as Running Mate

The ticket now turns to qualifying for the March 17 primary ballot in a still-unsettled Republican field.

Overview

  • Del Mar confirmed he will serve as Bailey’s lieutenant governor candidate, with a formal campaign announcement expected later this month.
  • Sources say the Bailey–Del Mar effort will emphasize business, public safety and education while softening past messaging on abortion and gun rights to court suburban voters.
  • The campaign is preparing to circulate petitions to secure a spot on the March 17, 2026 Republican primary ballot.
  • Gov. J.B. Pritzker is seeking a third consecutive term with Christian Mitchell as his running mate, after defeating Bailey 55% to 42% in 2022.
  • Other GOP hopefuls include Ted Dabrowski and DuPage County Sheriff James Mendrick, who has filed a defamation suit alleging a rival promoted a planned deepfake video against him.
