What did Calhoun base his political platform devotion to?

John C. Calhoun based his political platform on the principles of states' rights and the protection of minority interests, particularly in relation to the institution of slavery. He argued for a strict interpretation of the Constitution, advocating for the idea that states should have the authority to nullify Federal Laws they deemed unconstitutional. Calhoun's philosophy emphasized the need for a balance of power between the federal government and the states, which he believed was essential for preserving liberty and preventing tyranny. His devotion to these principles shaped his support for Southern interests and his opposition to federal intervention in state affairs.
