But slavery was not at that time the leading political question of the day. Parties were divided upon the subject of the Mexican war. While opposed to the war, Mr. Lincoln was in favor of voting for the necessary supplies and appropriations, and he took care, in an elaborate speech, to explain his position. He felt that it was his duty as a citizen and a patriot to see that the army which had been sent to Mexico should be properly sustained; but he did not for a moment concede that the war was just or necessary. As President Polk saw fit to construe such a vote as a formal approval of his action and of the war, Mr. Lincoln made an elaborate speech in arraignment of his interpretation. As this was Mr. Lincoln’s first speech in Congress, I shall make considerable quotations from it, partly to show where he stood on this important question, and partly to prove to my readers that he was no novice, but well qualified for the high position to which he had been elected by the suffrages of his fellow-citizens. I am quite aware that many of my young readers will skip this portion as uninteresting; but I hope that if in after years they are led to read this biography once more, they will count it worth while to read it. After reviewing and controverting the reasons assigned by the President for the statement that Mexico had invaded our soil, and that therefore “by the act of the Republic of Mexico a state of war exists between that Government and the United States,” Mr. Lincoln proceeds: “I am now through the whole of the President’s evidence; and it is a singular fact, that if any one should declare the President sent the army into the midst of a settlement of Mexican people who had never submitted, by consent or by force, to the authority of Texas or of the United States, and that _there_ and _thereby_ the first blood of the war was shed, there is not one word in all the President has said which would either admit or deny the declaration. In this strange omission chiefly consists the deception of the President’s evidence--an omission which it does seem to me could scarcely have occurred but by design. My way of living leads me to be about the courts of justice; and there I have sometimes seen a good lawyer struggling for his client’s neck, in a desperate case, employing every artifice to work round, befog, and cover up with many words some position pressed upon him by the prosecution, which he _dared_ not admit and yet _could_ not deny. Party bias may help to make it appear so; but, with all the allowance I can make for such bias, it still does appear to me that just such, and from such necessity, are the President’s struggles in this case.
