* * * * * _Necessity of our Organization._--Such is the national position of our party. We are a national party, established for national purposes, such as can be accomplished by a national party only. If the principles which we have at heart were supported openly, actively, constantly by either of the other parties, there would be no occasion for our organization. But whatever may have been, or whatever may now be, the opinions of individual members, it is undeniable, that, _as national parties_, they have never opposed Slavery in any form. Neither has ever sustained any measure for the abolition of Slavery in the District of Columbia, but, on the contrary, discountenanced all such measures. Neither has ever opposed, in any form, the coastwise slave-trade under the flag of the United States. Neither has ever opposed the extension of Slavery. Neither has ever striven to divorce the National Government from Slavery. Neither has ever labored to place the National Government openly, actively, and perpetually on the side of Freedom. Nor is there any assurance, satisfactory to persons not biased by political associations, that either of these organizations will ever, as a _national party_, espouse the cause of Freedom. Circumstances in the very constitution of these parties render it difficult, if not impossible, for them to act in this behalf. Constructed subtly with a view to political success, they are spread everywhere throughout the Union, and the principles which they uphold are pruned and modified to meet existing sentiment in different parts of the country. Neither can venture, as a party, to place itself on the side of Freedom, because, by such a course, it would disaffect that slaveholding support which is essential to its political success. The Antislavery resolutions adopted by legislatures at the North are regarded as expressions of individual or local opinion only, and not suffered to control the action of the national party. To such an extent is this carried, that Whigs of Massachusetts, professing immitigable hostility to Slavery, recently united in support of a candidate for the Presidency in whose behalf the eminent slaveholding Whig, Mr. Berrien, had "implored his fellow-citizens of Georgia, Whig and Democratic, to forget for a time their party divisions, and to know each other only as Southern men."
