In a dramatic shift for Illinois politics, Lieutenant Governor Juliana Stratton secured the Democratic nomination for the U.S. Senate, overcoming a well-funded campaign by Rep. Raja Krishnamoorthi. Bolstered by the political apparatus of Governor JB Pritzker and a surge in downstate support, Stratton now moves to the general election as the favorite to succeed long-serving Senator Dick Durbin.
The landscape of Illinois’ federal representation underwent a seismic shift on Tuesday night as Juliana Stratton rode a wave of progressive momentum and institutional backing to defeat Rep. Raja Krishnamoorthi. With approximately 82% of precincts reporting, Stratton held a commanding 39.6% to 33.6% lead, a gap of roughly 50,000 votes. The victory marks a successful “outsider” play by a sitting Lieutenant Governor who positioned herself against the “Washington experience” of her primary rivals.
The primary to replace Senator Dick Durbin, who has held the seat since 1997, was defined by a massive disparity in traditional fundraising that was ultimately neutralized by super PAC spending and strategic endorsements. Krishnamoorthi, a prolific fundraiser, had banked over $19 million prior to his launch and spent more than $27 million on television advertisements. Despite this “media blitz” that began in July 2025, Krishnamoorthi’s polling hit a persistent ceiling in the mid-30s.
The Chicago and Downstate Coalition
Stratton’s victory was built on a formidable coalition that united Chicago’s West Side with key downstate population centers. In the city of Chicago, Stratton dominated with 44% of the vote, compared to 25% for Rep. Robin Kelly and 23% for Krishnamoorthi.
While Krishnamoorthi maintained strength in the “collar counties” surrounding Cook, Stratton’s ability to win Will County and sweep through Springfield, Bloomington-Normal, and Champaign-Urbana proved decisive. This downstate surge suggests that Stratton’s message—focused on a $25 minimum wage, Medicaid for All, and the abolition of ICE—resonated beyond the progressive circles of Cook County.
The Pritzker Factor and PAC Warfare
The financial subtext of the race was a battle between individual campaign war chests and “unlimited” outside spending. While Stratton struggled with federal contribution limits, she benefited from the Illinois Future PAC, a super PAC largely bankrolled by Governor JB Pritzker. This allowed Stratton to combat Krishnamoorthi’s airtime advantage starting in January.
Conversely, Krishnamoorthi faced intense scrutiny over his donor list. Reports revealed more than $90,000 in contributions from donors with ties to President Donald Trump, including $30,000 from the CTO of Palantir, a company with significant contracts with immigration authorities. Though Krishnamoorthi donated an equivalent sum to immigrant rights groups, the headlines coincided with Operation Midway Blitz, an intensification of federal immigration enforcement that made “abolish ICE” a potent rallying cry for Stratton’s base.
Republican and Congressional Shifts
On the Republican side, former GOP Chair Don Tracy secured the nomination with 40% of the vote, comfortably ahead of Chicago attorney Jeannie Evans at 22%. Tracy’s general election platform centers on the cost of living, specifically targeting energy and healthcare expenses.
The primary also saw several “rare open seats” in the House settled:
-
9th District: Evanston Mayor Daniel Biss won with 30%, surviving a primary where candidates sparred over AIPAC alignments.
-
2nd District: Cook County Commissioner Donna Miller secured 40% in a crowded field.
-
8th District: Former U.S. Rep. Melissa Bean made a successful political return, winning with 32%.
-
7th District: State Rep. La Shawn Ford emerged from a 13-candidate field with 25% of the vote.
As Stratton prepares to face Tracy in November, the Democratic Party of Illinois appears to be moving toward a more populist, progressive platform. Her victory speech on the West Side emphasized “courage” as the fuel for a campaign that will now take the fight “straight to Donald Trump’s door.”
