Along with other American public institutions, Congress and the federal bureaucracy have fallen upon hard times. Each has been the target of much public scorn. Among academic theorists who have compared the contemporary roles of the bureaucracy and Congress, however, Congress has received the worst evaluation by far. It has often been treated as a more or less quaintly archaic institution, structurally unable to cope with the complexities of national issues. Samuel Huntington delineates several factors which he thinks tend to insulate Congress from an effective national policy-making role. Internally, the institutionalization of Congress has created a system of leadership selection which fragments authority and rewards and reinforces provincial perspectives. Externally, with rare exceptions, electoral turn-over is limited. Thus, the intake of new blood, especially in the House, is mostly dependent upon voluntary departures or biological processes. Equally important in Huntington's view are the characteristics of the congressmen themselves. They are, as many have pointed out, essentially local politicians oriented to local rather than national problems. Their incentives lie in looking ‘homeward’ to local constituencies rather than outward to the nation. Edward Shils has described their orientations as ‘those of the small town society’, suspicious of large organization and wary of complexity. Responsiveness to local interests, not comprehension of complex national policy problems, is the sine qua non of the congressman's political survival.
