"Beginning with a discussion of how the regime created by the Constitution requires a strong executive, it then moves to note the different attributes that emerge from the presidency's structure. Specifically, energy, secrecy, continuity, a national perspective, and a longer temporal horizon. The rest of the chapter describes how these attributes fit in with the presidency's constitutional duties and powers, providing the means to achieve the functional ends set by the Constitution. The framework for analyzing the relationship between the office's structure, duties, and powers are five presidential roles: chief executive, chief legislator, chief diplomat, commander-in-chief, and chief constitutionalist. Throughout the chapter it is also noted how this logic interacts with the other branches and points out those areas where the logic may have tensions or be ambiguous, to be resolved by political contestation"-- Provided by publisher.
