Incumbent Rep. Bob Latta secured the Republican nomination in Ohio's May 5 primary for the OH-05 House seat, facing Democrat Brian Shaver, who emerged from a four-way Democratic primary, in a district rated Solidly Republican by the Cook Political Report. Latta, representing northwest Ohio since 2007, benefits from the area's consistent GOP voting patterns, reinforced by 2025 redistricting that preserved the partisan lean. With no recent polling indicating a competitive contest and historical incumbency advantages in safe seats, traders reflect strong consensus on a Republican hold at 89.5%, though national midterm dynamics or unforeseen scandals could influence the November 3 general election outcome.
