Well maybe not in that case did they threaten but they did a lot of discussion about it and one state actually did secede from the central government.

"New England Secession Tradition-- The region of the United States that first tested the Union for its viability was New England. Its leaders seriously considered secession in 1804 over President Jefferson’s Louisiana Purchase; in 1808 over Jefferson’s Embargo of their trade; and most seriously in 1814, over issues surrounding “Mr. Madison’s War of 1812.” Secession was advocated by New England abolitionists from the 1830s on to 1860; and by John Quincy Adams and other New England leaders over the Mexican war and the annexation of Texas."

"Hartford Convention-In all, 26 delegates attended. The meetings were secret and no records of the proceedings were kept. Meetings continued through January 5, 1815. After choosing George Cabot as president, and Theodore Dwight as secretary, the present convention remained in close session for three continuous weeks. Surviving letters of contemporaries show that representative Federalists labored with these delegates to procure the secession of New England. Assembling amid rumors of treason and the execration of all the country west of the Hudson, its members were watched by an army officer who had been conveniently stationed in the vicinity. Cabot's journal of its proceedings, when it was eventually opened, was a meager sketch of formal proceedings; he made no record of yeas and nays, stated none of the amendments offered to the various reports, attached the name of no author to a single proposition. It is impossible to ascertain the speeches or votes of individual delegates."

"Vermont was not one of these states, but seceded from Britain on her own in 1777, and remained an independent republic before joining the Union in 1791."

Secession was a not an unusual or unknown theory in New England nor was it always unpopular.
