While young Root was leading the debate in the Assembly, Ambrose Spencer led it in the Senate. Spencer's apostacy produced a profound sensation in political circles. He had given no intimation of a change of political principles. Although still a young man, barely thirty-three, he had ranked among the foremost leaders of the Federalist party, having been honoured as an assistant attorney-general, a state senator, a member of the Council of Appointment, a friend of Hamilton, and the confidential adviser of Jay. The latter's heart might well sink within him to be abandoned by such a colleague at a time when the stability of the Union was insidiously attacked; nor ought Spencer to have been surprised that public rumour immediately set to work to find some reason for his change less simple and less honest, perhaps, than a dislike of the Federalist policy. Various causes have been given for his mysterious behaviour. Some thought him eager for a high mark of presidential favour, possibly a mission abroad, which was not warmly advocated by Hamilton; others believed that the bitter quarrel between Adams and Hamilton influenced him to desert a sinking party; but the rumour generally accepted by the Federalists ascribed it to his failure to become state comptroller in place of Samuel Jones, an office which he sought. It was recalled that shortly after Jones' appointment, Spencer raised the question, with some show of bitterness, that Jones' seat in the Senate should be declared vacant. Spencer denied the charges with expletives and with emphasis, treating the accusations as a calumny, and insisting that his change of principles occurred in the spring of 1798 before his re-election as senator. This antedated the alien and sedition measures, but not the appointment of Samuel Jones, making his conversion contemporary with the candidacy for governor of Chancellor Livingston, to whom he was related. It is not unlikely that he shared Livingston's confidence in an election and thought it a good time to join the party of his relative; but whether his change was a matter of principle, of self-interest, or of resentment, it bitterly stung the Federalists, who did not cease to assail him as a turncoat for the flesh-pots.[88] [Footnote 88: "Ambrose Spencer's politics were inconsistent enough to destroy the good name of any man in New England; but he became a chief-justice of ability and integrity."--Henry Adams, _History of the United States_, Vol. 1, p. 112.]
