Jedediah Peck was a member of Assembly from 1798 to 1804, and State Senator until 1808. Although looked up to by multitudes as the political leader of his time, Peck was noted at Albany for his shabbiness of dress. He wore coarse boots, which he never blackened. On one occasion, on the eve of an important debate, some wag at the tavern blackened one of Peck's boots. Peck, in dressing for the fray, did not recognize the shining boot, and having put on one began to search high and low for the other. At last, enlightened by the laughter of his comrades, he drew on the polished boot, and with his feet thus ill-matched strode into the Assembly chamber, where he delivered one of his most powerful speeches.

For many years Jedediah Peck unsuccessfully urged a bill for the abolition of imprisonment for debt, which was later adopted. His most permanent and valuable contribution to the welfare of posterity was the scheme for the common school system of the State, which he had long advocated, and of which, as chairman of the five commissioners appointed by the Governor in 1811, he became the author.[64]

Some of the asperities of political life in the early days of Otsego county may be inferred from certain affidavits, printed copies of which, such as were apparently used as campaign documents, were found among Judge Cooper's papers, endorsed in his handwriting, "Oath how I whipped Cochran." The Cochran referred to was a political opponent.

Jessie Hyde, of the town of Warren, being duly sworn, saith, that on the sixteenth day of October in the year 1799, he this deponent, did see James Cochran make an assault upon one William Cooper in the public highway. That the said William Cooper defended himself, and in the struggle Mr. Cochran, in a submissive manner, requested of Judge Cooper to let him go.

Personally appeared Stephen Ingalls, one of the constables of the town of Otsego, and being duly sworn, deposeth and saith, that he was present at the close of a bruising match between James Cochran Esq., and William Cooper Esq., on or about the sixteenth of October last, when the said James Cochran confessed to the said William Cooper these words: "I acknowledge you are too much of a buffer for me," at which time it was understood, as this deponent conceives, that Cochran was confessedly beaten.
