Nor is it by any means certain that General McClellan would not, once elected, consider himself the Chicago Platform, as Mr. Buchanan avowed himself to be the Cincinnati Platform. He has written a letter, to be sure, in which he has given it to be understood that he is in favor of continuing the war against the Rebels until they shall be subdued; but so did Mr. Polk, twenty yearn ago, write a letter on the Tariff of 1842 that was even more satisfactory to the Democratic Protectionists of those days than the letter of General McClellan can be to the War Democrats of these days. All of us recollect the famous Democratic blazon of 1844,--"Polk, Dallas, and the Tariff of '42!" It was under that sign that the Democrats conquered in Pennsylvania; and had they not conquered in Pennsylvania, they themselves would have been conquered in the nation. Mr. Polk and Mr. Dallas were the chief instruments used to break down the Tariff of '42, in less than two years after they had been elected to the first and second offices of the nation because they were believed to be its most ardent friends. Mr. Polk, as President, recommended that it should be changed, and employed all the influence of his high station to get the Tariff Bill of 1846 through Congress; and Mr. Dallas, who had been nominated for the Vice-Presidency with the express purpose of "catching" the votes of Protectionists, gave his casting vote in the Senate in favor of the new bill, which meant the repeal of the Tariff of '42. The Democrats are playing the same game now that they played in 1844, with this difference, that the stakes are ten thousand times greater now than they were then, and that their manner of play is far hardier than it was twenty years since. Then, the question, though important, related only to a point of internal policy; now, it relates to the national existence. Then, the Free-Traders did not offensively proclaim their intention to cheat the Protectionists; now, Mr. Fernando Wood and Mr. Vallandigham, and other leaders of the extreme left of the Democratic party, with insulting candor, avow that to cheat the country is the purpose which that party has in view. Mr. Vallandigham, who made the Chicago Platform, explicitly declares that that Platform and General McClellan's letter of acceptance do not agree; at the same time Mr. Wood, who is for peace to the knife, calmly tells us that General McClellan, as President, would do the work of the Democracy,--and we need no Daniel to interpret Mr. Wood's words. We mean no disrespect to General McClellan, on the contrary we treat him with perfect respect, when we say that we do not believe he has a higher sense of honor than Mr. Polk possessed; and as Mr. Polk became a tool in the hands of a faction,--being a Protectionist during the contest of '44, and an Anti-Protectionist after that contest had been decided in his favor,--so is it intended that General McClellan shall become a tool in the hands of another faction.
