A magisterial work, one of the most important studies of the presidency--indeed, of American politics--ever written...[Skowronek] comes very close to identifying the root problem affecting presidents...This is the all-important fact that the Constitution is unchanging and nondeveloped, while at all times intersecting with a social, economic, and political world that has undergone incessant development from the beginning. The whole work may be read as an extended, powerful, and penetrating meditation on some of the global consequences of this fact.
