Kuhner taught Modern US History at McGill University in Montreal from 1998 to 2000. In 2000, citing "the political correctness...prevalent in academia" on his website, he became an assistant national editor at the "Washington Times." He left in 2003 and worked for the Republican policy group the Ripon Society as communications director of the "Ripon Forum". He was the editor of the US news magazine website "Insight on the News" from October 2005 until its closing in May 2008. Simultaneously, Kuhner worked at the Thomas B. Fordham Institute, an education-policy organization, as its communications director. He was president of the Edmund Burke Institute for American Renewal, a now-dormant Washington D.C. think tank devoted to integrating minorities into the conservative movement. Until January 2012, the Burke Institute produced an online monthly magazine, "Reflections", to which he regularly contributed.
