HERSHEY (AP) – Pennsylvania’s Democrat governor and his Republican challenger met in their only formal appearance together in the fall campaign, in which moderator Alex Trebek of “Jeopardy!” fame needled the candidates on their mudslinging or exaggerations. Gov. Tom Wolf and GOP nominee Scott Wagner met at Monday night’s annual Pennsylvania Chamber of Business and Industry dinner in Hershey, attended by about 1,700 people. Wolf agreed to just one head-to-head encounter with Wagner. Trebek framed the 45-minute event as a conversational-style format, rather than a more traditional debate format that would highlight policy positions that are already well-known. Wolf is seeking a second term in Nov. 6’s election. Wagner served four years as a York County state senator, resigning in June, and runs a waste-hauling business.
