The election of George Clinton gave the party of Jefferson entire control of the State. It had the governor, the Legislature, and the Council of Appointment. It only remained to empower the Council to nominate as well as to confirm, and the boss system, begun in 1794, would have the sanction of law. For this purpose delegates, elected by the people, met at Albany on the 13th of October, 1801, and organised a constitutional convention by the election of Aaron Burr as president. Fortune had thus far been very good to Burr. At forty-five he stood one step only below the highest place in the nation, and now by a unanimous vote he became president of the second constitutional convention of the Empire State. His position was certainly imposing, but when the convention declared, as it did, that each member of the Council had the right to nominate as well as to confirm, Burr sealed DeWitt Clinton's power to overthrow and humiliate him.

In its uncompromising character DeWitt Clinton's dislike of Burr resembled Hamilton's, although for entirely different reasons. Hamilton thought him a dangerous man, guided neither by patriotism nor principle, who might at any moment throttle constitutional government and set up a dictatorship after the manner of Napoleon. Clinton's hostility arose from the jealousy of an ambitious rival who saw no room in New York for two Republican bosses. Accordingly, when the Council, which Jay had refused to reassemble, reconvened under the summons of Governor Clinton, it quickly disclosed the policy of destroying Burr and satisfying the Livingstons.[120] President Jefferson had already sent the Chancellor to France, and the Legislature had made John Armstrong, his brother-in-law, a United States senator. But enough of the Chancellor's family remained to fill other important offices, and the Council made Edward, a brother, mayor of New York; Thomas Tillotson, a brother-in-law, secretary of state; Morgan Lewis, a fourth brother-in-law, chief justice, and Brockholst Livingston, a cousin, justice of the Supreme Court.

Out of the spoils that remained, and there was an abundance, DeWitt Clinton and Ambrose Spencer helped themselves; and then they divided the balance between their relatives and supporters. Sylvanus Miller, an ardent and lifelong friend of the former, became surrogate of New York; Elisha Jenkins, who deserted the Federalists in company with Spencer, took John V. Henry's place as state comptroller; Richard Riker, the friend and second of Clinton in his famous duel with John Swartout, became district attorney in place of Cadwallader D. Colden, a worthy grandson of "Old Silver Locks," the distinguished colonial lieutenant-governor; John McKisson, a protégé of Spencer, took the clerkship of the Circuit Court from William Coleman, subsequently the brilliant editor of the Evening Post, established by Jay and Hamilton; and William Stewart, a brother-in-law of George Clinton, displaced Nathan W. Howell as assistant attorney-general. Thus the work of the political guillotine went on. It took sheriffs and surrogates; it spared neither county clerks nor justices of the peace; it left not a mayor of a city, nor a judge of a county. Even the residence of an appointee did not control. Sylvanus Miller of Ulster was made surrogate of New York with as much disregard of the people's wishes as Ruggles Hubbard of Rensselaer, who had visited the city but twice and knew nothing of its people or its life, was afterward made its sheriff.

When Clinton and Spencer finished their work a single Federalist, Josiah Ogden Hoffman, the attorney-general, remained in office, and he survived only until Ambrose Spencer could take his place. Soon afterward Spencer was advanced to the Supreme Court in place of Jacob Radcliff, a promotion that filled Federalists with the greatest alarm. Looking back upon the distinguished career of Chief Justice Spencer, it seems strange, almost ridiculous, in fact, that his appointment to the bench should have given rise to such fears; but Spencer had been the rudest, most ferocious opponent of all. The Federalists were afraid of him because they believed with William P. Van Ness, the young friend of Burr, that he was "governed by no principles or feelings except those which avarice and unprincipled ambition inspired."[121] Van Ness wrote with a pen dipped in gall, yet, if contemporary criticism be accepted, he did not exaggerate the feeling entertained for Spencer by the Federalists of that day. Like DeWitt Clinton, he was a bad hater, often insolent, sometimes haughty, and always arbitrary. After he left the Federalist party and became a member of the celebrated Council of 1801, he seemed over-zealous in his support of the men he had recently persecuted, and unnecessarily severe in his treatment of former associates. "The animosity of the apostate," said Van Ness, "cannot be controlled. Savage and relentless, he thirsts for vengeance. Such is emphatically the temper of Ambrose Spencer, who, after his conversion, was introduced to a seat in the Legislature, by his new friends, for the express purpose of perplexing and persecuting his old ones."[122] Spencer never got over being a violent partisan, but he was an impartial, honest judge. The strength of his intellect no one disputed, and if his political affiliations seemed to warp his judgment in affairs of state, it was none the less impartial and enlightened when brought to bear on difficult questions of law.

The timely resignation of John Armstrong from the United States Senate made room for DeWitt Clinton, who, however, a year later, resigned the senatorship to become mayor of New York. The inherent strength of the United States Senate rested, then as now, upon its constitutional endowment, but the small body of men composing it, having comparatively little to do and doing that little by general assent, with no record of their debates, evidently did not appreciate that it was the most powerful single chamber in any legislative body in the world. It is doubtful if the framers of the Constitution recognised the enormous power they had given it. Certainly DeWitt Clinton and his resigning colleagues did not appreciate that the combination of its legislative, executive, and judicial functions would one day practically dominate the Executive and the Congress, for the reason that its members are the constitutional advisers of the President, without whose assent no bill can become a law, no office can be filled, no officer of the government impeached, and no treaty made operative.

In taking leave of the United States Senate, Clinton probably gave little thought to the character of the place, whether it was a step up or a step down to the mayoralty. Just then he was engaged in the political annihilation of Aaron Burr, and he felt the necessity of entering the latter's stronghold to deprive him of influence. Out of six or seven thousand appointments made by the Council of Appointment not a friend of Aaron Burr got so much as the smallest crumb from the well-filled table. Even Burr himself, and his friend, John Swartout, were forced from the directorate of the Manhattan Bank that Burr had organised. "With astonishment," wrote William P. Van Ness, "it was observed that no man, however virtuous, however unspotted his life or his fame, could be advanced to the most unimportant appointment, unless he would submit to abandon all intercourse with Mr. Burr, vow opposition to his elevation, and like a feudal vassal pledge his personal services to traduce his character and circulate slander."[123]

Governor Clinton feebly opposed this wholesale slaughter by refusing to sign the minutes of the Council and by making written protests against its methods; but greater emphasis would doubtless have availed no more, since the constitutional convention had reduced the governor to the merest figurehead. His one vote out of five limited the extent of his prerogative. Power existed in the combine only, and so well did DeWitt Clinton control that when the famous Council of 1801 had finished its work nothing remained for succeeding Councils to do until Clinton, the prototype of the party boss, returned in 1806 to crush the Livingstons.

Occasionally a decapitated office-holder fiercely resented the Council's action, and, to make it sting the more, complimented the Governor for his patriotic and unselfish opposition. John V. Henry evidenced his disgust by ever after declining public office, though his party had opportunities of recognising his great ability and rewarding his fidelity. Ebenezer Foote, a bright lawyer, who took his removal from the clerkship of Delaware County very much to heart, opened fire on Ambrose Spencer, charging him with base and unworthy motives in separating from the Federalists. To this Spencer replied with characteristic rhetoric. "Your removal was an act of justice to the public, inasmuch as the veriest hypocrite and the most malignant villain in the State was deprived of the power of perpetuating mischief. If, as you insinuate, your interests have by your removal been materially affected, then, sir, like many men more honest than yourself, earn your bread by the sweat of your brow."[124]

At Washington, Jefferson had rewarded friends as openly as DeWitt Clinton took care of them in Albany. In telling the story, James A. Bayard of Delaware produced an oratorical sensation in the House of Representatives. "And now, sir, let me ask the honourable gentleman," said the congressman, in reply to William Giles' defence of the Virginia President, "what his reflections and belief will be when he observes that every man on whose vote the event of Mr. Jefferson's election hung has since been distinguished by presidential favour. Mr. Charles Pinckney of South Carolina was one of the most active, efficient and successful promoters of the election of the present chief magistrate, and he has since been appointed minister plenipotentiary to the court of Madrid—an appointment as high and honourable as any within the gift of the Executive. I know what was the value of the vote of Mr. Claiborne of Tennessee; the vote of a State was in his hands. Mr. Claiborne has since been raised to the high dignity of governor of the Mississippi Territory. I know how great, and how greatly felt, was the importance of the vote of Mr. Linn of New Jersey. The delegation of the State consists of five members; two of the delegation were decidedly for Mr. Jefferson, two were decidedly for Mr. Burr. Mr. Linn was considered as inclining to one side, but still doubtful; both parties looked up to him for the vote of New Jersey. He gave it to Mr. Jefferson; and Mr. Linn has since had the profitable office of supervisor of his district conferred upon him. Mr. Lyon of Vermont was in this instance an important man; he neutralised the vote of Vermont; his absence alone would have given the State to Mr. Burr. It was too much to give an office to Mr. Lyon; his character was low; but Mr. Lyon's son has been handsomely provided for in one of the executive offices. I shall add to the catalogue but the name of one more gentleman, Mr. Edward Livingston of New York. I knew well—full well I knew—the consequence of this gentleman. His means were not limited to his own vote; nay, I always considered more than the vote of New York within his power. Mr. Livingston has been made the attorney for the district of New York; the road of preferment has been opened to him, and his brother has been raised to the distinguished place of minister plenipotentiary to the French Republic."[125]

Albert Gallatin, Jefferson's secretary of the treasury, thought Burr less selfish than either the Clintons or the Livingstons, and, on the score of office-seeking, Gallatin was probably correct. But Burr, if without relatives, had several devoted friends whom he pressed for appointment, among them John Swartout for marshal, Daniel Gelston for collector, Theodorus Bailey for naval officer, and Matthew L. Davis for supervisor. Swartout succeeded, but DeWitt Clinton, getting wind of the scheme, entered an heroic protest to Jefferson, who quickly concurred in Clinton's wishes without so much as a conference with Gallatin or Burr. The latter, hearing rumours of the secret understanding, sent a sharp letter to Gallatin, pressing Davis' appointment on the ground of good faith, with a threat that he would no longer be trifled with; but Gallatin was helpless as well as ignorant, and the President silent. Davis' journey to Monticello developed nothing but Jefferson's insincerity, and on his return to New York the press laughed at his credulity.
