Could these elements be harmonized? Could the bolters from the Whig party overcome their traditional hatred of Martin Van Buren? If so, could the Liberty party men be prevailed upon to give up their chosen candidate, and labor for the election of the "foxy old politician" whose reputation for tricky and ambidextrous political methods had become proverbial? If not, could the Barnburners, with their large following, be united on the candidate of the Liberty party, or some new man? These questions had to be met; but preliminary to the nomination was the construction of a platform. This was accomplished without serious difficulty, and, considering the circumstances of the country, it was perhaps the most admirable declaration of principles ever promulgated by any party. It was chiefly the work of Mr. Chase, assisted by Charles Francis Adams, Benjamin F. Butler, and others, and it declared, among its pregnant and telling sentences, that "Congress has no more power to make a slave than to make a king," and that "it is the duty of the Federal Government to relieve itself of all responsibility for the existence or continuance of slavery wherever that Government possesses authority to legislate and is thus responsible for its existence." The reading of these declarations called forth thunders of applause, while the last plank in the platform "resolved, that we inscribe on our banner free soil, free speech, free labor, and free men, and under it we will fight on and fight ever, until a triumphant victory shall reward our exertions."
