Now, this showing up of Democracy, on the Slavery question, may look _shabby_ to many ultra Southern men, and it may induce them to charge that the Democratic party are _inconsistent_. We defend them against the charge of _inconsistency_, and maintain that what would be called _inconsistency_ here, is nothing but _Democracy_. For instance, A. O. P. Q. X. Y. Z. Nicholson, the editor of the great official organ of Democracy at Washington, said, editorially, and "by authority," so late as 1855: "IT IS NO PART OF THE CREED OF A DEMOCRAT, AS SUCH, TO ADVOCATE OR OPPOSE THE EXTENSION OF SLAVERY. HE MAY DO THE ONE OR THE OTHER, IN THE EXERCISE OF HIS RIGHTS AS A CITIZEN, AND NOT OFFEND AGAINST HIS DEMOCRATIC FEALTY!" Precisely so! A man may advocate the _abolition_ of slavery where it exists; he may, as a Black Republican, arm himself with Sharpe's rifle, and go into Kansas, and shoot down pro-slavery men, and still be a consistent Democrat, if he vote for the party, and stand by the nominees of the party conventions! Hence, all the factions at home and from abroad--all religions--all the ends and odds of God's creation are now associated together, and are battling in the same unholy cause, in the name of _Democracy_! And further to exhibit the inconsistency of this Democratic and Foreign party, it will be recollected that, in 1844, they nominated SILAS WRIGHT, of New York, for Vice-President, to run on the ticket with COL. POLK--a position he declined, because he would not agree to be _second best_ on the ticket. In a letter to JAMES H. TITUS, ESQ., bearing date April 15, 1847, MR. WRIGHT says: "If the question had been propounded to me at any period of my public life, Shall the arms of the Union be employed to conquer, or the money of the Union be used to purchase Territory now constitutionally free, for the purpose of planting Slavery upon it, I should have answered, No! And this answer to this question is the Wilmot Proviso, as I understand it. _I am surprised that any one should suppose me capable of entertaining any other opinion, or giving any other answer as to such a proposition._" Now, if SILAS WRIGHT, one of the great "Northern lights" of Democracy, held these sentiments in 1847, what must they have been in 1844, when that party sought to elevate him to the second office within the gift of the nation? But we are just reminded of what is said in "the law and the prophets," that is to say, "_It is no part of the creed of a Democrat_, AS SUCH, _to advocate or oppose the extension of slavery!_" What a party!
