An unintended consequence of wide single-party identification was reduced party discipline. Rather than political harmony, factions arose within the party. Monroe attempted to improve discipline by appointing leading statesmen to his Cabinet, including Secretary of State John Quincy Adams of Massachusetts, Secretary of the Treasury William H. Crawford of Georgia, and Secretary of War John C. Calhoun of South Carolina. General Andrew Jackson of Tennessee led high-profile military missions. Only House Speaker Henry Clay of Kentucky held political power independent of Monroe. He refused to join the cabinet and remained critical of the administration.
