1	The Federalist No. 70 Alexander Hamilton Energy in the Executive is a leading character in the definition of good government. A feeble Executive implies a feeble execution of the government. A feeble execution is but another phrase for a bad execution; and a government ill executed, whatever it may be in theory, must be, in practice, a bad government.
2	Why We Need a Strong Executive [Energy in the Executive] is essential to the protection of the community against foreign attacks; [Energy in the Executive] is not less essential to the steady administration of the laws; to the protection of property against those irregular and high-handed combinations which sometimes interrupt the ordinary course of justice; to the security of liberty against the enterprises and assaults of ambition, of faction, and of anarchy.
3	Structuring an Energetic Executive Taking it for granted, therefore, that all men of sense will agree in the necessity of an energetic Executive, it will only remain to inquire, what are the ingredients which constitute this energy? How far can they be combined with those other ingredients which constitute safety in the republican sense? And how far does this combination characterize the plan which has been reported by the convention?
4	A Strong and Responsible Presidency The ingredients which constitute energy in the Executive are, first, unity; secondly, duration; thirdly, an adequate provision for its support; fourthly, competent powers. The ingredients which constitute safety in the republican sense are, first, a due dependence on the people, secondly, a due responsibility.
5	Decision, Activity, Secrecy, and Dispatch That unity is conducive to energy will not be disputed. Decision, activity, secrecy, and dispatch will generally characterize the proceedings of one man in a much more eminent degree than the proceedings of any greater number; and in proportion as the number is increased, these qualities will be diminished.
6	Plural Legislature In the legislature, promptitude of decision is oftener an evil than a benefit. The differences of opinion, and the jarrings of parties in that department of the government, though they may sometimes obstruct salutary plans, yet often promote deliberation and circumspection, and serve to check excesses in the majority. When a resolution too is once taken, the opposition must be at an end. That resolution is a law, and resistance to it punishable.
7	Unified Executive No favorable circumstances palliate or atone for the disadvantages of dissension in the executive department. Here, they are pure and unmixed. There is no point at which they cease to operate. They serve to embarrass and weaken the execution of the plan or measure to which they relate, from the first step to the final conclusion of it. They constantly counteract those qualities in the Executive which are the most necessary ingredients in its composition -- vigor and expedition, and this without any counterbalancing good. In the conduct of war, in which the energy of the Executive is the bulwark of the national security, every thing would be to be apprehended from its plurality.
8	Executive Responsibility One of the weightiest objections to a plurality in the Executive is that it tends to conceal faults and destroy responsibility. Responsibility is of two kinds -- to censure and to punishment. The first is the more important of the two, especially in an elective office. Man, in public trust, will much oftener act in such a manner as to render him unworthy of being any longer trusted, than in such a manner as to make him obnoxious to legal punishment. But the multiplication of the Executive adds to the difficulty of detection in either case.
9	Determining Responsibility It often becomes impossible, amidst mutual accusations, to determine on whom the blame or the punishment of a pernicious measure, or series of pernicious measures, ought really to fall. It is shifted from one to another with so much dexterity, and under such plausible appearances, that the public opinion is left in suspense about the real author.
10	Plurality of the Executive Undermines Faithful Execution of the Laws It is evident from these considerations, that the plurality of the Executive tends to deprive the people of the two greatest securities they can have for the faithful exercise of any delegated power
11	Faithful Execution (cont.) first, the restraints of public opinion, which lose their efficacy, as well on account of the division of the censure attendant on bad measures among a number, as on account of the uncertainty on whom it ought to fall; and, second, the opportunity of discovering with facility and clearness the misconduct of the persons they trust, in order either to their removal from office or to their actual punishment in cases which admit of it.
12	Responsibility in a Monarchy In England, the king is a perpetual magistrate; and it is a maxim which has obtained for the sake of the public peace, that he is unaccountable for his administration, and his person sacred. Nothing, therefore, can be wiser in that kingdom, than to annex to the king a constitutional council, who may be responsible to the nation for the advice they give. Without this, there would be no responsibility whatever in the executive department
13	Monarch Compared to President But in a republic, where every magistrate ought to be personally responsible for his behavior in office the reason which in the British Constitution dictates the propriety of a council, not only ceases to apply, but turns against the institution. In the monarchy of Great Britain, it furnishes a substitute for the prohibited responsibility of the chief magistrate, which serves in some degree as a hostage to the national justice for his good behavior. In the American republic, it would serve to destroy, or would greatly diminish, the intended and necessary responsibility of the Chief Magistrate himself.
14	UNITY of the Executive A Distinguishing Feature of the Constitution Prior to the appearance of the Constitution, I rarely met with an intelligent man from any of the States, who did not admit, as the result of experience, that the UNITY of the executive of this State was one of the best of the distinguishing features of our constitution.
15	Postscript The Founders conspicuously and very consciously declined to sap the Executive's strength in the same way they had weakened the Legislature: by dividing the executive power. Proposals to have multiple executives, or a council of advisers with separate authority were rejected. (Scalia, dissenting in Morrison v. Olson, 1988)
