The Presidency

We give our correspondent, Mr. Trench, a chanco to be heard, wilhou! endoTsing all his views or statements, or coinciding in his anticipations of antislavery nction by proslavery parties. His subject however, is eminently important and practical; and so far as a discusión of it at present can be made to promote a . harmony of views among Liberty men, and subserve the progresa of antislavery principies, it is well. We believe thnt a difference of opinión on the Presidential question exists among Liberty men. - Some are desirous of making a Liberty nomination, without any regard to the state of feeling in other pnrties : while another portion of the party think that circumstances may render a separate . nomination by the Liberty party unnecessary. If our memory serves us. Dr. Bailey, now the Editor of the Era, threw out thia auggestion some time since ; and in a Utc number of that paper, we noticed that J. G Whittrer, its associate editor, expressed the opinión in effect, that the dïtöerenceabelween Independent DemOcfais, Young Whigs, and Liberty men, were ofsuch a nature that they would not thereby be precluding from agreeing upon, nominating and supporting the same Presidential candidate. It is obvious that to make thoir action in tha highest degree effective, Liberty men ought to be unitkd on the proper course to be pursued. We believe that in the end they willcordially and substantially ag:ee. It is yet, however, too early to fix upon all the details of action for the Presidential campaign. Many things may occur within the next twelve months that will essentiaüy alter the aspect of poliiical nffairs. A Nationnl Convention of Antisiavery men, irrespective of party, to delibérate on common mensures for the advancement of the cause.has been proposed, and a Committee of twelve now have the time and place of meeting under con. sideration. Should such a meeting be held, its action might greatly affect, and perhaps determine the result of the enBuring Presidential canvass. But the great principies on which we hould all be determincd to act ought now to be fully estnblished in our minds, and spread abrond before .the world. Liber'.y men have not enlisted in the antislavery cause as a child's play.not for the purpose merely of nequiring a balance of power between the other parties. They have great ohjects in view, for the forwarding of which evcry movrment should be directed. VVo think, therefore, thnt by whatever partie Presidential candidates may be nominated, no Liberty man can consistently or wisely support any who will not most unequivocally give their influence forthosetwo great points which are necessary frr the political regenerotion of the country -the exclusión of Slave olders from National Offices, and the RErEAL OF THE Sl.AVE LaW8.
