Durbin Steps Down After Decades of Service
Senator Dick Durbin, the second-highest-ranking Democrat in the U.S. Senate, announced on April 23, 2025, that he will not seek reelection in 2026, concluding a congressional career spanning over four decades. In a video message, Durbin said, “I truly love the job of being a United States Senator. But in my heart, I know it’s time to pass the torch,” according to Durbin’s official statement.
Durbin’s tenure has been marked by significant legislative achievements, including championing immigration reform and serving as a powerful voice on the Senate Judiciary Committee. His retirement announcement followed a notably low fundraising report that intensified speculation about his future.

Stratton Declares Candidacy; Others Poised to Join
Illinois Lieutenant Governor Juliana Stratton quickly entered the race, launching her Senate campaign with a focus on uplifting the state’s middle class. She becomes the first major Democrat to officially declare her candidacy, as reported by NBC Chicago.
Representatives Raja Krishnamoorthi and Lauren Underwood are widely expected to follow. Krishnamoorthi enters with a formidable $19 million campaign fund, while Underwood has amassed over $1 million in cash on hand, according to Axios.
Leadership Implications Within the Senate
Durbin’s departure doesn’t just open a Senate seat—it also shakes up Democratic leadership. As Senate Majority Whip since 2005, Durbin’s exit launches a quiet competition to succeed him. Senators Brian Schatz and Amy Klobuchar are reportedly among those considering bids for the leadership role, according to Axios.
This leadership shift comes at a pivotal moment, with Senate Majority Leader Chuck Schumer forecasting a regained Democratic majority by 2027, even as the party contends with internal rifts and critical elections, as noted in Axios Hill Leaders.
A Competitive Primary Ahead
With the field rapidly taking shape, the Democratic primary for Durbin’s seat is expected to be fiercely competitive. In addition to Stratton, Krishnamoorthi, and Underwood, other names floated include former Chicago Mayor Rahm Emanuel and Congresswoman Robin Kelly. Chicago Sun-Times reports that at least a dozen candidates may join the contest.
Polling data cited by Wikipedia’s 2026 Illinois Senate election entry shows Underwood narrowly leading the pack with 33%, followed by Krishnamoorthi at 30%, Stratton at 16%, and Kelly trailing with 10%.
As Illinois heads toward a critical election, the race to replace Durbin will serve as a barometer for the future direction of the Democratic Party—both in the Midwest and on the national stage.
