Republican Ohio gubernatorial candidate Vivek Ramaswamy records a video before the Warren County Republicans Lincoln Day Dinner at the Great Wolf Lodge in Mason, Ohio, Friday, April 10, 2026.
Ohio's Republican primary for governor is a few weeks away, but there are few signs that the top candidate sees it as a competitive race. Nonetheless, the primary season has exposed potential vulnerabilities for former presidential candidate Vivek Ramaswamy. The biotech billionaire is focused mostly on his likely general election opponent, Democrat Amy Acton. She's the state’s former public health director. Ramaswamy feels so assured of gliding through the May 5 vote that his campaign has all but ignored his GOP opponent so far. That's Casey Putsch, an engineer and vehicle designer who calls himself “The Car Guy.”
