Abstract: | This article proposes a diffusion of responsibility perspective in analyzing post–World War II politics in the United States. Many analysts test the American system by a responsible party perspective, proposing reforms that will orient the system toward the goals of that model. Divided government has characterized much of the period since 1945 and identifiable (and wholly constitutional) politics has accompanied that development. The diffusion of responsibility alternative is characterized by a separated presidency, an expansive Congress, competition between the branches for shared power, and, absent a crisis, a tendency toward perpetuation. |
