Both president, Andrew Jackson and Vice president John C. Calhoun were southern planters and defenders of the institution of slavery. But, in 1830, Jackson, raising his glass in a toast at an annual Jefferson Dy dinner glared down the table at Calhoun and said, "Our Federal Union: It must be preserved!" In his own answering toast, Calhoun rose to say, "The Union, next to our liberty, most dear!" Discuss the differences between Jackson and Calhoun and explain why the clash between the two men erupted in 1830. Explain in detail and refer back to Harry L. Watson's book Liberty and Power.
