Juliana Stratton won the Illinois Democratic primary for the U.S. Senate on Tuesday, emerging from a crowded and closely watched contest that quickly became one of the state’s most important political tests of 2026. Her victory sends the lieutenant governor into the general election as the Democratic nominee to replace retiring Sen. Dick Durbin, whose decision to step aside opened a rare Senate vacancy in a state where such opportunities do not come often.
The race drew unusual national attention long before the first votes were counted. Part of that interest came from the seat itself: Sen. Dick Durbin, now 81, is retiring after five terms in the Senate, bringing to a close one of the longest and most influential careers in modern Illinois politics. His departure created a rare open-seat contest and turned the Democratic primary into the main event in a state where Republicans have not won a statewide election in more than a decade.
Stratton, a progressive backed by Gov. J.B. Pritzker, had trailed Rep. Raja Krishnamoorthi in polling for much of the race before momentum shifted in the closing weeks. A wave of spending from Pritzker’s orbit and a hardening voter mood on immigration helped change the shape of the contest, weakening the standing of Krishnamoorthi, who was widely viewed as the more moderate candidate.
She also faced pressure from her left. Rep. Robin Kelly competed for progressive voters and raised the possibility of a split in that bloc, but the threat never fully materialized. Kelly won less than 20% of the vote, according to the Associated Press, leaving Stratton with enough support to break through in a crowded and highly competitive primary.
Juliana Stratton entered the contest with the backing of Gov. J.B. Pritzker, a major advantage in a campaign that was as much about political strength inside Illinois as it was about the future direction of the Democratic Party. The Pritzker Illinois Senate race dynamic gave her campaign added weight from the start, turning the primary into a test of both her appeal and the governor’s influence.
Pritzker’s endorsement gave Juliana Stratton immediate credibility with party loyalists and made the primary a closely watched measure of his standing at a moment when his national profile continues to rise. With Illinois remaining firmly Democratic in federal races, the winner of the primary was widely seen as the favorite to capture the seat in November.
That reality now gives Juliana Stratton an even larger platform as she prepares to face former Illinois Republican Party chair Don Tracy in the general election. Her path to November comes after a primary in which immigration emerged as one of the clearest dividing lines between the top candidates, especially as Chicago continued to deal with the political fallout from recent ICE raids and the street protests that followed.
Juliana Stratton took the harder line in the closing stretch of the campaign. She called for the abolition of ICE, while Raja Krishnamoorthi struck a more measured tone and argued instead against what he described as “Trump’s ICE” in a barrage of late campaign ads aired across Illinois. The contrast helped sharpen the choice for Democratic voters looking at the race through the lens of immigration enforcement and federal power.
A November victory would not only keep the seat in Democratic hands, but would also place Stratton in a small and significant chapter of U.S. political history. If she wins, Juliana Stratton would become the 15th Black U.S. senator in American history.

According to Reuters and the Associated Press, Stratton defeated 10 other Democratic candidates, including U.S. Reps. Raja Krishnamoorthi and Robin Kelly. The result was notable not only because of the field she beat, but because she did it despite trailing badly in fundraising for much of the race.
Krishnamoorthi had built a large financial edge, yet Stratton’s support from Pritzker and other prominent Democrats helped her close the gap at the most important moment.
That support mattered because the campaign grew into a sharper fight over ideology, momentum and message. For Juliana Stratton, the primary became a chance to present herself as a candidate willing to take clearer positions than her rivals at a moment when Democratic voters were demanding sharper contrasts.
Immigration emerged as one of the defining issues of the race, especially in and around Chicago, where federal enforcement actions and the wider debate over border policy fueled voter frustration and shaped campaign rhetoric. Juliana Stratton used that climate to underline her more progressive stance and to separate herself from the rest of the field.
She framed her campaign as a direct challenge to Donald Trump and the broader Republican agenda, while arguing for forceful action on immigration reform. That message helped Juliana Stratton strengthen her standing in a competitive primary that was increasingly driven by urgency, identity and turnout.
Her win is also politically significant for another reason. The Illinois Senate contest has been watched closely as a measure of Pritzker’s strength within the Democratic Party, especially as speculation around his long-term national ambitions continues. By helping lift Stratton to the nomination, the governor showed that his endorsement still carries serious weight in a state he already dominates politically. That alone will draw attention well beyond Illinois.
For Stratton, the primary victory now shifts the campaign into a new phase. She is set to face Republican Don Tracy, the former Illinois Republican Party chair, in the November general election.
Illinois remains a strongly Democratic state in federal contests, which gives Stratton a clear advantage heading into the fall, but the race will still serve as an important marker in the broader national fight for control of Congress and in the debate over what kind of candidates Democratic voters want to send to Washington.
The result also marks a generational turning point in Illinois politics. Durbin’s retirement signaled the end of a long chapter in the state’s Democratic leadership, and Juliana Stratton’s nomination places a newer face at the center of that transition.
Pritzker underscored the stakes by arguing that Illinois will need strong Democratic voices in Washington as Donald Trump remains in the White House. He said the country and the state are facing historic and unprecedented challenges, and made clear that he wants Juliana Stratton working alongside Sen. Tammy Duckworth when the next Senate term begins on January 3, 2027.
If she wins in November, Juliana Stratton would make history as one of a very small number of Black women ever elected to the U.S. Senate, adding another layer of significance to an already consequential race.
She survived a competitive field, validated the confidence that Pritzker placed in her campaign and positioned herself as the leading Democrat in one of the year’s most closely followed statewide races. In Illinois, that is a major victory. Nationally, it may prove to be an early sign of where Democratic politics is heading next.
