Recent polling averages show Democrat Amy Acton leading Republican Vivek Ramaswamy by roughly three to five points in the November 3 contest to succeed term-limited Governor Mike DeWine. Trader consensus on Polymarket reflects this edge, with Acton at 81.5 percent implied probability. The decisive recent development has been backlash against a Ramaswamy campaign ad featuring Acton’s estranged mother, which drew bipartisan criticism—including from DeWine—and prompted Cook Political Report and Sabato’s Crystal Ball to shift the race to Lean Democratic. Acton has maintained steady advantages among independents and in suburban areas, while Ramaswamy’s heavy advertising spending has not reversed the polling trend. The contest remains within historical margins for an open-seat race in a state that has favored Republicans in presidential voting.
