Illinois Democratic primaries showcased Governor JB Pritzker’s political influence, particularly through his substantial financial support for Lt. Governor Juliana Stratton, who won the U.S. Senate primary and could become the sixth Black woman in the Senate if victorious in the general election. Stratton’s campaign, backed by prominent endorsements and opposition to ICE, overcame strong fundraising and polling by her main rival, Representative Raja Krishnamoorthi, highlighting Pritzker’s sway in state politics ahead of a possible 2028 presidential bid. Additionally, outside spending from pro-Israel, cryptocurrency, and AI groups totaled over $52 million across key races, reflecting the growing impact of specialized interest groups on primary outcomes.
