John Randolph Tucker, Appletons' Cyclopædia of American Biography (1900)
“ Calhoun saw the south in a minority in all branches of the government, and he desired, by giving to the south a concurrent and distinct voice in the organism of our system, to secure her against invasion of her rights by a hostile majority, and thus to make her safe in the union. When the abolition party was small in numbers and weak in organization, and public men treated its menaces with contempt, Mr. Calhoun saw the cloud like a man's hand which was to overspread our political heavens. ”
