Incumbent Republican Mike Turner faces Democratic challenger Kristina Knickerbocker in Ohio’s 10th district, rated R+4 by the Cook Partisan Voter Index and carried by Trump by roughly eight points in 2024. Recent July 2026 polls show Turner holding a modest lead that narrows or ties after voters hear candidate profiles, reflecting Knickerbocker’s improving name recognition and the district’s generic ballot near parity. Forecasters classify the seat as Likely or Solid Republican, yet the wide dispersion across margin buckets in trader pricing underscores uncertainty over turnout, late-cycle messaging, and any national midterm shifts that could compress or expand the final Republican edge before November 3.
