Illinois Primary: Lt. Gov. Stratton Wins Senate Nomination, Setting Up Fall Battle as Pritzker Eyes Third Term

Lieutenant Governor Juliana Stratton emerged as the Democratic nominee for U.S. Senate from Illinois on Tuesday night, defeating two veteran House members in a primary that laid bare the tensions within the state party and set up a high-stakes November race to fill the seat of retiring Senate legend Dick Durbin. Stratton's victory, fueled in large part by the financial backing of Governor JB Pritzker and his allied super PAC, gave the governor an early indication that his formidable political apparatus can deliver results heading into his own reelection campaign.

Stratton, who has served as Illinois' first Black lieutenant governor since 2019, defeated Rep. Raja Krishnamoorthi of the Chicago suburbs and Rep. Robin Kelly of the south suburbs in a three-way contest that had been fiercely competitive for months. Final results showed Stratton carrying Cook County — home to Chicago and the bulk of Illinois Democratic voters — by a comfortable margin, while Krishnamoorthi ran strongly in the collar counties and Kelly held her base on the South Side and south suburbs. Pritzker had poured money into a super PAC backing Stratton and made personal calls on her behalf in the final days of the campaign.

On the Republican side, former state Representative Darren Bailey secured the GOP nomination for governor in a four-way primary, setting up a rematch with Pritzker after his loss in the 2022 general election. Bailey, a downstate farmer and evangelical Christian whose hardline positions helped Pritzker win by nearly 12 percentage points four years ago, once again outlasted more moderate challengers with strong support from rural and exurban conservatives. Republicans argued Bailey's name recognition and core voter loyalty outweighed the electability concerns raised by party strategists.

Pritzker, who ran unopposed in the Democratic primary, is widely regarded as a potential 2028 presidential contender and is expected to use a commanding reelection campaign as a national launching pad. The billionaire governor has built one of the most well-funded political operations in state history and has become a vocal national voice on abortion rights, immigration, and economic policy. Democrats privately expect Pritzker to win reelection comfortably given the state's deep blue lean, but acknowledge that high energy prices from the Iran war and a slowing national economy could complicate the political environment by November.

Perhaps the most closely watched race of the evening was a hotly contested Democratic primary for a Chicago-area U.S. House seat, where progressive incumbent Kat Abughazaleh lost her bid for reelection in a result that generated significant attention from national progressive organizations. The defeat was seen by some strategists as a signal that the electorate has shifted since the Iran war began, with hawkish positions becoming more politically viable even in deeply Democratic districts.

The Illinois results also produced a notable outcome in the race to succeed Stratton as lieutenant governor, with several competitive primaries for down-ballot offices reflecting a Democratic Party still navigating its identity in the Trump era. State party chair Lisa Hernandez said the evening's results demonstrated the party's strength from Chicago to the collar counties and expressed confidence about November's general election matchups across the board. With the primary concluded, attention now turns to the fall campaigns, with control of Illinois' Senate seat seen as critical to Democrats' chances of winning back the Senate majority in 2026.
