Book excerpt: It is no longer sufficient to examine discrete nation-states in isolation from each other. In Politics in North America: Redefining Continental Relations, prominent authors from Canada, the United States, and Mexico explore the politics of redefining the institutional, economic, geographic, and cultural boundaries of North America. The contributors argue that the study of politics in the twenty-first century requires simultaneous attention to all levels (local, national, and international) as well as, increasingly, to continents. This argument is explored through the historical and contemporary social and political forces that have created competing visions of what it means to belong to a North American political community. In this process, new debates emerge in the book concerning the appropriate role for the state, as well as the meaning of sovereignty, democracy, and rights.
