Duckworth’s endorsement comes after Gov. JB Pritzker endorsed Stratton on Friday, one day after she entered the Senate contest.

Gov. JB Pritzker has made his choice for who he'd like to replace retiring Sen. Dick Durbin: Lt. Gov. Juliana Stratton. Why it matters: Pritzker is the top Democrat in the state, with deep pockets and a firm control of the state party.
