The Ohio 1st congressional district race stays tightly contested as redistricting shifted boundaries to favor Republicans more than prior maps, with the area showing a narrow Trump edge in 2024 presidential results. Incumbent Democrat Greg Landsman holds a modest polling lead over Republican Eric Conroy in the most recent survey, reflecting incumbency advantages in the Cincinnati metro area balanced against broader midterm headwinds and local turnout patterns among suburban and urban voters. Primary results cleared the field for both nominees without major disruptions, leaving limited separation in early forecasts. Key variables that could widen margins include final voter mobilization efforts, any late national economic or policy signals, or shifts in undecided and independent support before November 3.
