Incumbent Jim Jordan runs unopposed in the May 5 Republican primary for Ohio's 4th Congressional District, a solidly Republican seat with a Cook Partisan Voting Index of R+21, fueling trader consensus at 92% for a GOP victory on November 3. All major race ratings—Solid Republican from Cook Political Report, Inside Elections, and Sabato's Crystal Ball—reflect the district's history of lopsided wins, including Jordan's 68.5% margin in 2024 amid 71% Republican presidential turnout. Democrat Joshua Kolasinski, the sole primary candidate after Tamie Wilson's withdrawal, reports no fundraising as of late 2025. While late scandals, health issues, or a national Democratic wave could shift odds, structural advantages present significant barriers.
