The Republican Party’s historic Convention Address, preparatory to its first nominating convention in June, argued that “the Government of the United States is not administered in accordance with the Constitution, or for the preservation and prosperity of the American Union; but that its powers are systematically wielded for the promotion and extension of the Interest of Slavery.” Despite the “sentiment of the Founding Fathers,” who sought to contain slavery, the country’s history demonstrates “the progress of slavery towards ascendancy in the federal government.” The Convention urges adherents to send delegates to Philadelphia in June, “to nominate candidates for the Presidency and Vice-Presidency of the United States.”
