Traders on Polymarket overwhelmingly favor Juliana Stratton (100%) to win the Illinois Democratic Senate primary, driven by her high name recognition as former lieutenant governor, strong fundraising totals exceeding $2 million, and key endorsements from Governor JB Pritzker and Senate Democratic leaders. Recent polls show her leading by 40+ points among declared candidates, with fragmented opposition from lesser-known challengers like Raja Krishnamoorthi and Robin Kelly splitting anti-Stratton votes. This consensus reflects skin-in-the-game bets on her organizational edge in Chicago and Cook County. Realistic challenges include a late high-profile entrant consolidating support or an unforeseen scandal eroding her lead before the March primary, though current momentum points to a decisive victory.
