Addresses questions surrounding the persistence of partisan conflict and legislation supporting various forms of protectionism amid bipartisan support for a liberal trade regime. Lays out a foundation for a nested-games framework and overviews American trade policy since 1934, then looks in depth at the dynamics of the electoral competition game and its effects on trade policy. Examines effects of institutional structure on the politics of trade policy, and analyzes the politics of trade in the aftermath of Republican reforms following the 1994 midterm elections.
