The following summer, considerable public opinion was gathered in the North in support of Tallmadge`s proposal. Much of this anti-Missouri atmosphere, as it was called, was born out of the true belief that slavery was morally false. Political opportunity has been mixed with moral convictions. Many prominent anti-Missouri men had been active in the federalist party, which appeared to be in the process of disintegration; she was accused of looking for a problem to rebuild her party. Federalist leaders of the anti-Missouri group have pushed some northern Democrats to reconsider their support for the Tallmadge amendment and to support a compromise that would undermine the federalist party`s stimulus efforts. To compensate for the number of slave states and free states, the northern Massachusetts region, the District of Maine, was eventually admitted to the United States as a free state to become the separate state of Maine. This was done only through a compromise on slavery in Missouri and the federal territories of the American West.  The Missouri admission debate also raised the issue of sectoral balance, as the 11-state country was divided equally between slave states and free states. Admitting Missouri as a slave state would reverse the balance of the Senate, consisting of two senators per state, to the benefit of the slave states. That is what has made the northern states that they have Maine as a free state. Maine was admitted in 1820, and Missouri in 1821, but until 1836, when Arkansas was admitted, no other states were added.
 The disorder of Republican superiority caused by the merger raised fears in the Southern states that a Free State Party could take shape if Congress failed to reach an agreement on Missouri and slavery and risked threatening the eminence of the South. U.S. Secretary of State John Quincy Adams of Massachusetts suspected that the political constellation already existed for such a section party.   It was indisputable that the federalists were striving to regain some degree of political participation in national politics. However, there was no basis for the accusation that the federalists had guided Tallmadge in his anti-slavery measures, and there was no indication that a New York-based King Clinton alliance was attempting to establish an anti-slavery party on the ruins of the Republican Party. The assertions of the southern interests of “plot-by-plot” slavery or “consolidation” as a threat to the Union have misunderstood the forces at work in the Missouri crisis. The core of opposition to slavery in Louisiana Purchase was informed by Jefferson`s egalitarian principles and not by a federalist revival.   White House Chief of Staff John Kelly sparked controversy Monday night when he declared on the fox-news program “The Ingraham Angle” that “lack of compromise has led to civil war.” As many historians have already seen, historically, it is difficult… The Missouri compromise, as it was known, remained in force for about 30 years before being repealed by the Kansas-Nebraska Act of 1854.
