Let Douglas cry "awful," "anarchy," "revolution," as much as he would, Lincoln's arguments against the Dred Scott decision appealed to common sense and won him commendation all over the country. Even the radical leaders of the party in the East—Seward, Sumner, Theodore Parker—began to notice him, to read his speeches, to consider his arguments.
With every month of 1857 Lincoln grew stronger, and his election in Illinois as United States senatorial candidate in 1858 against Douglas would have been insured if Douglas had not suddenly broken with Buchanan and his party in a way which won him the hearty sympathy and respect of a large part of the Republicans of the North. By a flagrantly unfair vote the pro-slavery leaders of Kansas had secured the adoption of the Lecompton Constitution allowing slavery in the State. President Buchanan urged Congress to admit Kansas with her bogus Constitution. Douglas, who would not sanction so base an injustice, opposed the measure, voting with the Republicans steadily against the admission. The Buchananists, outraged at what they called "Douglas's apostasy," broke with him. Then it was that a part of the Republican party, notably Horace Greeley at the head of the New York "Tribune," struck by the boldness and nobility of Douglas's opposition, began to hope to win him over from the Democrats to the Republicans. Their first step was to counsel the leaders of their party in Illinois to put up no candidate against Douglas for the United States senatorship in 1858.
Lincoln saw this change on the part of the Republican leaders with dismay. "Greeley is not doing me right," he said. "... I am a true Republican, and have been tried already in the hottest part of the anti-slavery fight; and yet I find him taking up Douglas, a veritable dodger,—once a tool of the South, now its enemy,—and pushing him to the front." He grew so restless over the returning popularity of Douglas among the Republicans that Herndon, his law-partner, determined to go East to find out the real feeling of the Eastern leaders towards Lincoln. Herndon had, for a long time, been in correspondence with the leading abolitionists and had no difficulty in getting interviews. The returns he brought back from his canvass were not altogether reassuring. Seward, Sumner, Phillips, Garrison, Beecher, Theodore Parker, all spoke favorably of Lincoln and Seward sent him word that the Republicans would never take up so slippery a quantity as Douglas had proved himself. But Greeley—the all-important Greeley—was lukewarm. "The Republican standard is too high," he told Herndon. "We want something practical.... Douglas is a brave man. Forget the past and sustain the righteous." "Good God, righteous, eh!" groaned Herndon in his letter to Lincoln.
But though the encouragement which came to Lincoln from the East in the spring of 1858 was meagre, that which came from Illinois was abundant. There the Republicans supported him in whole-hearted devotion. In June, the State convention, meeting in Springfield to nominate its candidate for Senator, declared that Abraham Lincoln was its first and only choice as the successor of Stephen A. Douglas. The press was jubilant. "Unanimity is a weak word," wrote the editor of the Bloomington "Pantagraph," "to express the universal and intense feeling of the convention. Lincoln! Lincoln!! LINCOLN!!! was the cry everywhere, whenever the senatorship was alluded to. Delegates from Chicago and from Cairo, from the Wabash and the Illinois, from the north, the center, and the south, were alike fierce with enthusiasm, whenever that loved name was breathed. Enemies at home and misjudging friends abroad, who have looked for dissension among us on the question of the senatorship, will please take notice that our nomination is a unanimous one; and that, in the event of a Republican majority in the next Legislature, no other name than Lincoln's will be mentioned, or thought of, by a solitary Republican legislator. One little incident in the convention was a pleasing illustration of the universality of the Lincoln sentiment. Cook County had brought a banner into the assemblage inscribed, 'Cook County for Abraham Lincoln.' During a pause in the proceedings, a delegate from another county rose and proposed, with the consent of the Cook County delegation, 'to amend the banner by substituting for "Cook County" the word which I hold in my hand,' at the same time unrolling a scroll, and revealing the word 'Illinois' in huge capitals. The Cook delegation promptly accepted the amendment, and amidst a perfect hurricane of hurrahs, the banner was duly altered to express the sentiment of the whole Republican party of the State, thus: 'Illinois for Abraham Lincoln.'"
On the evening of the day of his nomination, Lincoln addressed his constituents. The first paragraph of his speech gave the key to the campaign he proposed. "A house divided against itself cannot stand. I believe this government cannot endure permanently half slave and half free. I do not expect the house to fall—but I do expect it will cease to be divided. It will become all one thing or all the other."
Then followed the famous charge of conspiracy against the slavery advocates, the charge that Pierce, Buchanan, Chief Justice Taney, and Douglas had been making a concerted effort to legalize the institution of slavery "in all the States, old as well as new, North as well as South." He marshaled one after another of the measures that the pro-slavery leaders had secured in the past four years, and clinched the argument by one of his inimitable illustrations.
"When we see a lot of framed timbers, different portions of which we know have been gotten out of different times and places and by different workmen,—Stephen, Franklin, Roger and James,[A] for instance,—and we see these timbers joined together, and see they exactly make the frame of a house or a mill, all the tenons and mortises exactly fitting, and all the lengths and proportions of the different pieces exactly adapted to their respective places, and not a piece too many or too few, not omitting even the scaffolding—or, if a single piece be lacking, we see the place in the frame exactly fitted and prepared yet to bring such a piece in—in such a case we find it impossible not to believe that Stephen and Franklin and Roger and James all understood one another from the beginning, and all worked upon a common plan or draft, drawn up before the first blow was struck."
The speech was severely criticised by Lincoln's friends. It was too radical. It was sectional. He heard the complaints unmoved. "If I had to draw a pen across my record," he said, one day, "and erase my whole life from sight, and I had one poor gift of choice left as to what I should save from the wreck, I should choose that speech and leave it to the world unerased."
The speech, was, in fact, one of great political adroitness. It forced Douglas to do exactly what he did not want to do in Illinois; explain his own record during the past four years; explain the true meaning of the Kansas-Nebraska bill; discuss the Dred Scott decision; say whether or not he thought slavery so good a thing that the country could afford to extend it instead of confining it where it would be in course of gradual extinction. Douglas wanted the Republicans of Illinois to follow Greeley's advice: "Forgive the past." He wanted to make the most among them of his really noble revolt against the attempt of his party to fasten an unjust constitution on Kansas. Lincoln would not allow him to bask for an instant in the sun of that revolt. He crowded him step by step through his party's record, and compelled him to face what he called the "profound central truth" of the Republican party, "slavery is wrong and ought to be dealt with as wrong."
But it was at once evident that Douglas did not mean to meet the issue squarely. He called the doctrine of Lincoln's "house-divided-against-itself" speech "sectionalism"; his charge of conspiracy "false"; his talk of the wrong of slavery extension "abolitionism." This went on for a month. Then Lincoln resolved to force Douglas to meet his arguments, and challenged him to a series of joint debates. Douglas was not pleased. His reply to the challenge was irritable, even slightly insolent. To those of his friends who talked with him privately of the contest, he said: "I do not feel, between you and me, that I want to go into this debate. The whole country knows me, and has me measured. Lincoln, as regards myself, is comparatively unknown, and if he gets the best of this debate,—and I want to say he is the ablest man the Republicans have got,—I shall lose everything and Lincoln will gain everything. Should I win, I shall gain but little. I do not want to go into a debate with Abe." Publicly, however, he carried off the prospect confidently, even jauntily. "Mr. Lincoln," he said patronizingly, "is a kind, amiable, intelligent gentleman." In the meantime his constituents boasted loudly of the fine spectacle they were going to give the State—"the Little Giant chawing up Old Abe!"
