On October 5, the three candidates for Ohio Secretary of State debated each other. See this story. The three candidates are Democrat Maryellen O’Shaughnessy, Republican Jon Husted, and Libertarian Charlie Earl. Ballot Access News has been tracking debate inclusion starting in 1994, and this is the first time any Ohio debate for statewide office has included both major party nominees along with any minor party or independent candidate in a debate, except for the special election for Attorney General in 2008. Thanks to Kevin Knedler for the link.
Ohio will hold another three-party debate on October 6, for the three candidates for Auditor.
