The convention discussed removing the three-fifths compromise which gave slave states more power in Congress and requiring a two-thirds vote in Congress for the admission of new states, declarations of war, and creating laws restricting trade. The Federalists also discussed their grievances with the Louisiana Purchase and the Embargo of 1807. However, weeks after the convention's end, news of Major General Andrew Jackson's overwhelming victory in New Orleans swept over the Northeast, discrediting and disgracing the Federalists, resulting in their elimination as a major national political force.
