Nevertheless, the opposition in Congress persisted in misrepresenting the President's purposes. It was pointed out that the republics to the south very generally believed that the United States was pledged by Monroe's message to make common cause with them when their independence was threatened. "Are we prepared," asked Hayne, of South Carolina, "to send ministers to the Congress of Panama for the purpose of making effectual this pledge of President Monroe as construed by the present administration and understood by the Spanish-American states?" With greater sincerity Southern Representatives protested against participating in a congress which proposed to discuss the suppression of the slave trade and the future of Hayti. "Slavery in all its bearings," said Hayne, "is a question of extreme delicacy, concerning which there is but one safe rule either for the States in which it exists or for the Union. It must ever be treated as a domestic question. To foreign governments the language of the United States must be that the question of slavery concerns the peace and safety of our political family, and that we cannot allow it to be discussed." Least of all, he continued, could the United States touch the question of the independence of Hayti in connection with revolutionary governments which had marched to victory under the banner of universal emancipation and which had permitted men of color to command their armies and enter their legislative halls. In the end the Administration had its way and the nominations were confirmed; but the delay was most unfortunate. On their way to the Isthmus, one of the delegates died, and the other arrived too late to take part in the congress. From the viewpoint of domestic politics, the controversy over the mission was only an incident in the evolution of a party within the bosom of the Democratic party. The animus of the opposition is revealed in the often-quoted remark of Martin Van Buren, who was trying to drill the varied elements in the Senate into a coherent organization: "Yes, they have beaten us by a few votes, after a hard battle; but if they had only taken the other side and refused the mission, we should have had them."
