Vivek Ramaswamy won Ohio’s Republican primary for governor on May 5, 2026, capturing 82.5% of the vote and sweeping all 88 counties in the state. The biotech billionaire and former 2024 presidential candidate defeated Casey Putsch, a northwest Ohio car designer and racing team owner, who received 17.5% of the vote, according to NPR and NBC News.
Ramaswamy’s dominant primary performance set up a general election matchup against Democrat Amy Acton, the former state health director who won her party’s nomination unopposed. The race has since emerged as one of the most closely watched gubernatorial contests in the nation, with recent polling showing a competitive battle ahead of the November 3 general election.
The Ohio Republican Party had endorsed Ramaswamy in May 2025, solidifying his position as the presumptive GOP nominee more than a year before the primary. Ramaswamy selected state Senate President Rob McColley of northwest Ohio as his running mate for lieutenant governor, according to PBS. His campaign emphasized his business background and outsider appeal, positioning him as a continuation of the Trump movement in Ohio politics.
Despite his commanding primary victory, the general election has tightened considerably. Recent polling from July 2026 shows the race is highly competitive. According to the Cook Political Report, which moved the race from “leans Republican” to “toss-up” on July 16, both candidates have significant support. An AARP poll conducted in late June showed Acton leading 47% to 44%, while a New York Times/Siena poll from the same period had the candidates tied at 47% each, and a Fox News poll showed Acton ahead 50% to 49%. The general election remains months away, and polling continues to show movement in both directions.
Acton has also been competitive in fundraising. According to Signal Ohio, Acton had raised nearly $11.5 million by mid-2026, while Ramaswamy had raised $9.6 million. The fundraising disparity reflects the tightness of the race and the Democratic Party’s investment in what is being viewed as a winnable seat in a state that has trended Republican in recent years.
Ramaswamy’s path to the general election was significantly smoother than Acton’s. In addition to Putsch, Ramaswamy faced Heather Hill in the Republican primary, but neither challenger mounted a serious challenge to his candidacy. His sweep of all Ohio counties underscored the depth of his support within the Republican base, even as the general election has proven far more competitive than his primary performance suggested.
