CHICAGO — Gov. JB Pritzker emerged as the kingmaker in deep-blue Illinois after pouring millions of dollars and staking his political reputation to deliver his hand-picked Senate candidate a primary victory on Tuesday.

The result strengthens Pritzker’s standing within his party at a critical moment, as he prepares for a November gubernatorial campaign for his third term and looks ahead to a potential presidential run in 2028.

“It’s going to reflect well on him,” retiring Rep. Jan Schakowsky said Tuesday night shortly after Lt. Gov. Juliana Stratton was declared the winner in the Democratic primary for Illinois Senate. 

Robyn Gabel, the Illinois House Majority Leader, added: “I think it will show that he has coattails, and that he has a big following, and that people respect his opinions on who to vote for.”

Pritzker has built a reputation as an influential governor by leveraging institutional authority, strong party support, and his own vast financial resources to shape policy statewide, including addressing energy challenges, cost-of-living concerns and making infrastructure improvements. With Democrats holding control of the state legislature, he has also been able to further strengthen his dominance in Springfield.

And on the national stage, Pritzker has positioned himself among the chief antagonists of President Donald Trump, regularly attacking his immigration enforcement surges, among other issues.

Pritzker’s grip on the party was on full display in downtown Chicago, where he celebrated his uncontested gubernatorial primary victory by touting his accomplishments and attacking Trump as Illinois Democrats stood behind him.

“For working families, the Trump presidency has been an unmitigated disaster. Oil prices are up. Measles is back. Farms are folding. Tariffs have raised the price of groceries and cars, and Illinoisans have been sent abroad to fight another Middle East war,” Pritzker told dozens of cheering supporters. “In response, what is the Illinois Republican Party doing to help everyday people? Nothing.”

The crowd’s enthusiasm was aided by an open bar — a detail noted by some attendees after reports circulated from the watch party of Stratton’s well-funded opponent, Rep. Raja Krishnamoorthi, that his campaign was charging for drinks at the event.

Pritzker, who put millions of dollars into a super PAC supporting Stratton and campaigned regularly alongside his former running mate, brushed off concerns that a potential Stratton loss could tarnish his image. Another candidate he supported, Brad Schneider, won the Democratic nomination for Illinois’ 10th Congressional District.

“I’m not choosing candidates because I’ve taken a poll ahead of time and decided that I can only support a candidate that I know absolutely 100 percent is going to win otherwise,” Pritzker said at a candidate luncheon at Manny’s Deli on Chicago’s near South Side before polls closed. “Here’s what I know, when you’ve got somebody that is hyper-qualified for the job, that’s who I’m supporting.”

But later at Stratton’s watch party on Chicago’s West Side, Pritzker, who belongs to one of the nation’s wealthiest families, acknowledged the stake he held in Tuesday’s outcome.

“A lot of people have suggested this was personal to me,” he told hundreds of Stratton campaign staff and supporters, his voice noticeably strained late into the evening. “They were right. It was.”

The fractious Senate primary was defined by massive spending, racial dynamics and lingering intraparty rivalries. Krishnamoorthi had a $30 million war chest and significant outside support but couldn’t compete with Pritzker’s financial muscle and institutional backing of Stratton.

Rep. Robin Kelly, who came in third in the race, drew criticism from some for potentially splitting the Black vote. She, like Stratton, is Black and there were fears they’d cancel one another out, opening a path for Krishnamoorthi, who took advantage of that and even ran ads propping up Kelly to give himself an edge.

Rep. Yvette Clarke (D-N.Y.), the chair of the Congressional Black Caucus, which backed Kelly, issued a rebuke of Pritzker’s involvement in the race earlier this month, accusing the billionaire governor of trying to “tip the scales in Illinois” which she said was “beyond frustrating.”

Kelly reiterated that sentiment before polls closed Tuesday.

“He’s put his thumb on the race. Seventy-three percent of her donations came from one family,” Kelly said Tuesday afternoon, referring to Pritzker’s financial backing of Stratton.

The tensions between Pritzker and Kelly date back to a 2022 power struggle over control of the Illinois Democratic Party, when Kelly was pushed out amid concerns from Pritzker’s allies about her ability to fundraise while serving in Congress. While both sides have since publicly downplayed the feud, the Senate primary reopened old wounds with outside groups and Democratic factions lining up behind different candidates.

Another CBC member, Sen. Cory Booker of New Jersey, who previously ran for the White House, said on Capitol Hill prior to polls closing in Illinois that “it would be a damn shame if Robin Kelly” lost.

“Isn’t it a shame that I don’t have billions of dollars?” Booker said. “Look … the way the rules are right now, JB Pritzker as the governor of that state is free to support anybody he wants and he has a tremendous amount of resources. I hold no ill will there.”

Illinois state Rep. Kam Buckner, the speaker pro tempore and a member of the national Democratic Legislative Campaign Committee, defended Pritzker getting involved in the race.

“Political capital is a lot like financial capital, it does not grow because you admire it. It grows because you deploy it,” Buckner said in an interview. “He’s putting his political equity into circulation, which I think is the right thing for him to do.”
