Post-primary polls have yet to emerge following Ohio's May 5, 2026, contests, where Democrat Amy Acton advanced unopposed and Republican Vivek Ramaswamy secured the GOP nomination over Casey Putsch amid some intraparty controversy including rigging claims. Pre-primary surveys from April, like Bowling Green State University's Ramaswamy 48%-Acton 47% and Echelon Insights' 49%-44% Republican edge, averaged to a toss-up, aligning with trader consensus pricing Democrats at 53.5% implied probability in this open-seat race after term-limited incumbent Mike DeWine. Acton's familiarity as former health director contrasts Ramaswamy's outsider biotech entrepreneur profile, keeping dynamics tight; separation could arise from debates, endorsements, turnout in battleground suburbs, or economic shifts ahead of the November 3 general election.
