Simon Kiss is an Assistant Professor at Wilfrid Laurier University. Kiss became interested in the role of the news media in the political process after working for a political party at the Legislative Assembly.  His dissertation argued that changes in the provincial economy, the political party system, individual leadership style and the political economy of the media drove important changes in the government’s communication and marketing bureaucracy.  This has had deleterious effects in the capacity for citizens to hold their elected officials to account via their representatives.  Parallel changes are evident in other jurisdictions in Canada and at the federal level.  Today, he continues to write on the role of the media in the political and policy process in Canada.
