Ohio's 2026 Secretary of State race remains tightly contested ahead of the November 3 general election, with traders assigning Robert Sprague a narrow edge over Allison Russo in a state where partisan balance and turnout patterns often decide statewide contests. Sprague, the Republican nominee and current treasurer, has emphasized election security measures including expanded voter ID and registration checks, while Russo, the Democratic nominee and former House minority leader, has prioritized ballot access, transparency in administration, and limits on partisan influence. The presence of Libertarian Tom Pruss adds a minor third option, but the outcome hinges primarily on the major-party split. Early voting has begun, and any shifts in polling averages, endorsements from key groups, or developments around related ballot measures like voter ID rules could widen the gap in implied probabilities before Election Day.
