Forecast probabilities

  • Amy Acton: 77%
  • Vivek Ramaswamy: 23%

Reasoning

Amy Acton is the more likely winner, with a 77.0% chance, while Vivek Ramaswamy retains a substantial 23.0% chance. Recent polling and the fallout from Ramaswamy’s attack ad favor Acton, but Ohio’s Republican lean and the possibility of polling error keep this from being a sure thing.

Amy Acton: The edge in the late evidence

Several of the most relevant surveys put Acton ahead. Rasmussen and Suffolk each showed her leading by four points; Marist showed a seven-point advantage, and a private poll conducted after the ad controversy put her eight points ahead. A Republican-commissioned poll reportedly found the same eight-point gap, up from a narrower deficit beforehand. [a3] [e1] [e18] [e19] [e20]

The campaign’s most dramatic development may have hurt Ramaswamy more than it helped him. His ad featuring Acton’s estranged mother drew criticism from both parties, including Gov. Mike DeWine, and the Republican internal polling suggests many voters who saw it reacted in Acton’s favor. [e3] [e5] [e7] [e19] Acton also appears better positioned with independents: Ramaswamy’s net rating among them was reported at a record low for a Republican gubernatorial nominee, while the latest poll described Acton as holding a large lead with independent voters. [e14] [a3]

Other signals point in the same direction, though they are not wholly independent of the polling and ad controversy. Cook and Sabato moved the race to Lean Democrat, Decision Desk HQ gave Acton a 60% chance, and prediction markets put her chances higher still. [e4] [e17] [e26] [e34] Acton’s recent fundraising was stronger, although Ramaswamy’s overall campaign resources and allied advertising remained formidable. [e35] [e36] [e37]

Vivek Ramaswamy: The durable Republican case

Ohio’s political baseline is a real counterweight to Acton’s polling lead. Trump carried the state by 11 points in 2024, and no Democrat has won the governorship since 2006. [a2] [a3] [a11] A polling miss of a few points toward Republicans could therefore turn a modest Acton lead into a close race or a Ramaswamy victory.

There is also evidence that the race has not moved uniformly toward Acton. Echelon found Ramaswamy two points ahead, and ActiVote also showed him in front, though its survey was less current than the final-week polling. [e28] [e21] Republicans and their allies spent far more on advertising than Democrats, and Ramaswamy had additional ad reservations. Trump, Vance, and DeWine also backed him, giving him prominent surrogates and a route to mobilize Republican voters. [e37] [e8] [e50] [e16]

Why the balance favors Acton, but not decisively

The evidence is stronger for Acton than for Ramaswamy: multiple recent polls show her ahead, the ad controversy appears to have worsened Ramaswamy’s standing, and forecasters and markets shifted toward her. But those indicators must be weighed against Ohio’s Republican history, mixed polling, substantial Republican spending, and the possibility that surveys understate Republican support. The available results tracker reports no Election Day vote totals or call, so the forecast remains a judgment from pre-election evidence rather than counted votes. [a2]

Taken together, those factors support the aggregated forecast: Amy Acton 77.0%; Vivek Ramaswamy 23.0%.
