It was a matter of course that Mr. Colfax should go with all his heart into the great struggle of 1860. He felt and understood with unusual earnestness and clearness the importance of the principles involved, and the hazards of the political campaign. Into a paragraph or two written some time before the Chicago nomination, he condensed a whole code of political wisdom, and can now be seen to have pointed out Abraham Lincoln as the best candidate, by describing the political availability and ethical soundness of the position Mr. Lincoln then occupied. He wrote: "We differ somewhat from those ardent cotemporaries who demand the nomination of their favorite representative man, whether popular or unpopular, and who insist that this must be done, even if we are defeated. We do agree with them in declaring that we shall go for no man who does not prefer free labor and its extension, to slave labor and its extension,--who though mindful of the impartiality which should characterize the Executive of the whole Union, will not fail to rebuke all new plots for making the government the propagandist of slavery, and compel promptly and efficiently the suppression of that horrible slave-trade which the whole civilized world has banned as infamous, piratical and accursed. But in a Republican National Convention, if any man could be found, North, South, East or West, whose integrity, whose life, and whose avowals rendered him unquestionably safe on these questions, and yet who could yet poll one, two or three hundred thousand votes more than any one else, we believe it would be both wisdom and duty, patriotism and policy, to nominate him by acclamation and thus render the contest an assured success from its very opening. We hope to see 1866 realize the famed motto of Augustine--"In essentials unity, in non-essentials liberty, in all things charity." That is very broad and sound sense. It was in exact accordance with this doctrine and with these intimations as to who was the right man, that Mr. Lincoln was nominated, according to the desire of Mr. Colfax's heart; and in the coming campaign in his own very important state of Indiana, he did most valuable service in assuring the victory.
