COLUMBUS, Ohio (WCMH) -- Ohio's state Treasurer Robert Sprague is considering a run for Ohio's highest office, newly filed paperwork shows. Sprague filed a Designation of Treasurer document on Friday, the same day Lt. Gov. Jon Husted was appointed Ohio's newest Senator. The designation was for a change in office, with "Governor" listed as the new office Sprague is seeking. A Designation of Treasurer must be filed with the state before a candidate campaign committee, PAC, campaign fund or political party purchases anything or raises any money. Designations of Treasurer act as the official registration documents for campaign committees. Billionaire Vivek Ramaswamy to run for Ohio governor Sprague, a Republican, has yet to announce an official gubernatorial run, but the form listed him as a candidate for Governor in 2026. The filing also listed a campaign committee named Sprague for Ohio, which owns an up-to-date website under the same name. The website does not expressly mention a run for governor, but it is up-to-date and offers space to donate to his campaign, despite not stating what campaign it is. Sprague is not the only one eyeing the Governor's desk. Dr. Amy Acton, who helped lead Ohio's early pandemic response, announced her run for Governor on Jan. 7. Ohio billionaire and "DOGE" appointee Vivek Ramaswamy is also reportedly looking toward the role, as is Attorney General Dave Yost, who has posted vague videos hinting toward a governor run and who told NBC4 he's looking toward a higher office. Sprague hails from Findlay and has been Ohio's treasurer since 2019. Before stepping into the role, he served as a state Representative and as auditor and treasurer for the city of Findlay. He lives in Findlay with his wife, Amanda, and their five children.
