U.S. Senator Dick Durbin’s announcement earlier this week not to seek re-election in 2026 has sparked the beginning of a competitive race within the Democratic Party for Illinois’ open Senate seat.
As the state prepares for a crucial primary election in about 10 months, potential candidates are gearing up for what could be one of the most closely watched contests in recent memory.
Political analysts predict the field could include as many as a dozen candidates, with at least one statewide official already declaring her intention to run.
“We’re just so fortunate to have such a deep bench,” remarked Delmarie Cobb, a Democratic political consultant, highlighting Illinois’ array of viable candidates. “Not many states can say that.”
In a state that consistently leans Democratic, the winner of the primary is highly likely to secure the Senate seat come the general election. However, a prominent Republican contender is reportedly considering entering the race, which could add an intriguing dynamic to the contest.
### Candidates to Watch
With Durbin’s exit, several notable names have emerged as potential candidates for his Senate seat.
**Lt. Gov. Juliana Stratton (D)** has wasted no time in announcing her candidacy just 48 hours after Durbin’s announcement. She has garnered the endorsement of Governor JB Pritzker, highlighting the strong support behind her campaign.
Stratton made history as the state’s first Black lieutenant governor and has a track record of legislative engagement during her tenure, particularly on issues such as criminal justice reform and food insecurity.
**U.S. Rep. Raja Krisnamoorthi (D)**, who has represented parts of Chicago’s suburbs since 2016, is another strong candidate, fueled by a robust fundraising record boasting around $19 million in campaign funds. Known for his attention to detail and legislative effectiveness, Krisnamoorthi has focused on elevating issues connected to national security and economic relations with China.
Then we have **U.S. Rep. Robin Kelly (D)**, who represents Chicago’s southern suburbs and has signaled that she will formally announce her candidacy in the coming week. Kelly emphasizes her legislative effectiveness—a critical factor in her potential campaign. She has actively worked on issues such as gun violence and healthcare disparities. Notably, she also serves as the chair of the Democratic Party of Illinois, which could enhance her visibility and organizational support in the race.
**U.S. Rep. Lauren Underwood (D)** has also emerged as a strong contender, having made history in 2018 as the youngest Black woman elected to Congress. Her moderate stance has helped her gain traction as she addresses health care and infrastructure issues pertinent to her constituency. Early polling showed Underwood and Krisnamoorthi in a statistical tie, suggesting she has considerable recognition among voters.
Other prominent figures include **Rahm Emanuel**, the former mayor of Chicago and White House chief of staff, who has been active in public discussions about future roles he might pursue, including the Senate seat. Emanuel’s connections and experience could provide a significant advantage, though his potential candidacy remains speculative.
**Illinois Treasurer Michael Frerichs**, who has held office since 2014, is also contemplating his entry into the race. While he acknowledges the strong backing Stratton has from Pritzker, he believes that voter sentiments will ultimately decide the election.
On the Republican side, **U.S. Rep. Darin LaHood (R)** is weighing a potential run for the Senate seat. Representing central and northern rural parts of Illinois, LaHood faces an uphill battle in a predominately blue state, but his ongoing considerations reflect the competitive atmosphere surrounding the race.
### Early Polling Insights
A recent poll conducted prior to Durbin’s announcement offers a glimpse of the competitive nature of the race. It indicates that Underwood and Krisnamoorthi are statistically tied, each drawing significant support among Democratic primary voters.
The poll, carried out by the Democratic polling firm 314 Action, surveyed 773 likely Democratic voters in March. It revealed Underwood leading with 33%, followed closely by Krisnamoorthi at 30%, while Stratton held 16% and Kelly garnered 10%, with an additional 10% undecided.
Underwood’s solid name recognition, with 77% of respondents aware of her and 57% providing opinions, places her in a favorable position moving into the primary.
### Implications of Durbin’s Exit
Durbin’s decision has created a seismic shift in Illinois politics, opening the door for a diverse group of candidates eager to take the mantle. As each contender begins to outline their platforms, voters will need to consider the array of prominent issues that could shape the direction of the Democratic Party in Illinois.
The anticipation surrounding the primary will continue to grow as more candidates potentially enter the race, each bringing their unique perspectives and strategies to address the pressing needs of constituents.
While the Democratic candidate is expected to have a clear advantage in a general election, particularly given Illinois’ predominantly blue voting history, the Republican challenger could still present an interesting challenge, especially amid evolving political dynamics nationwide.
As we move closer to the critical 2026 primary season, the prospects of this Senate race will capture the attention of not just Illinois voters, but political observers across the country, eager to see how this competition unfolds.
With various narratives emerging and well-established figures stepping forward, the ability of these candidates to engage with and motivate voters will be crucial.
As the race begins to take shape, the Illinois Senate seat remains a focal point for discussion, debate, and candidacy declarations in the months to come.
