between the two lists was "owing doubtless to the hurry in which [Hamilton's] memorandum was made out." A known error in Hamilton's list—Hamilton incorrectly ascribed No. 54 to John Jay, when in fact, Jay wrote No. 64—provided some evidence for Madison's suggestion. Statistical analysis has been undertaken on several occasions in attempts to accurately identify the author of each individual essay. After examining word choice and writing style, studies generally agree that the disputed essays were written by James Madison. However, there are notable exceptions maintaining that some of the essays which are now widely attributed to Madison were, in fact, collaborative efforts. Influence on the ratification debates The Federalist Papers were written to support the ratification of the Constitution, specifically in New York. Whether they succeeded in this mission is questionable. Separate ratification proceedings took place in each state, and the essays were not reliably reprinted outside of New York; furthermore, by the time the series was well underway, a number of important states had already ratified it, for instance Pennsylvania on December 12. New York held out until July 26; certainly The Federalist was more important there than anywhere else, but Furtwangler argues that it "could hardly rival other major forces in the ratification contests"—specifically, these forces included the personal influence of well-known Federalists, for instance Hamilton and Jay, and Anti-Federalists, including Governor George Clinton. Further, by the time New York came to a vote, ten states had already ratified the Constitution and it had thus already passed—only nine states had to ratify it for the new government to be established among them; the ratification by Virginia, the tenth state, placed pressure on New York to ratify. In light of that, Furtwangler observes, "New York's refusal would make that state an odd outsider." Only 19 Federalists were elected to New York's ratification convention, compared to the Anti-Federalists' 46 delegates. While New York did indeed ratify the Constitution on July 26, the lack of public support for pro-Constitution Federalists has led historian John Kaminski to suggest that the impact of The Federalist on New York citizens was "negligible". As for Virginia, which ratified the Constitution only at its convention on June 25, Hamilton writes in a letter to Madison that the collected edition of The Federalist had been sent to Virginia; Furtwangler presumes that it was to act as a "debater's handbook for the convention there", though he claims
