He had nothing to do with the tariff of 1828. In his first message he suggested that some modifications of it were desirable, and pointed out that the public debt would soon be paid, and it would be advisable to reduce certain of the duties. But modification was too mild a word to suit the South Carolinians. The law was the outcome of the clamor of many selfish interests, and Congressmen opposed altogether to protection had helped to make it as bad as possible, hoping that it might in the end be defeated. When it passed, the South Carolina legislature vigorously protested, and began at once to debate about the best plan of resistance. The plan finally preferred was for the State to declare the law unconstitutional, and therefore null and void, and call on other States to join in the declaration. If the national government tried to enforce the law in South Carolina, she would protect her citizens, and as the final resort withdraw from the Union. The plan was first placed before the American people in an "Exposition and Protest" adopted by the South Carolina legislature in 1828; and the real author of that famous document, though the fact was not then known, was the Vice-President, Calhoun. The associate of Clay in those acts which had made a beginning of internal improvements and of protection, long a statesman of the strong-government school, Calhoun had been led by the distress and discontent of his own people to examine the Constitution again, "in order," as he said afterwards, "to ascertain fully the nature and character of our political system," and had now come to a change of views.
