The close attention bestowed on its delivery, the hearty applause that greeted its telling points, and the enthusiastic comments of the Republican journals next morning showed that Lincoln's Cooper Institute speech had taken New York by storm. It was printed in full in four of the leading New York dailies, and at once went into large circulation in carefully edited pamphlet editions. From New York, Lincoln made a tour of speech-making through several of the New England States, and was everywhere received with enthusiastic welcome and listened to with an eagerness that bore a marked result in their spring elections. The interest of the factory men who listened to these addresses was equaled, perhaps excelled, by the gratified surprise of college professors when they heard the style and method of a popular Western orator that would bear the test of their professional criticism and compare with the best examples in their standard text-books.

The attitude of the Democratic party in the coming presidential campaign was now also rapidly taking shape. Great curiosity existed whether the radical differences between its Northern and Southern wings could by any possibility be removed or adjusted, whether the adherents of Douglas and those of Buchanan could be brought to join in a common platform and in the support of a single candidate. The Democratic leaders in the Southern States had become more and more out-spoken in their pro-slavery demands. They had advanced step by step from the repeal of the Missouri Compromise in 1854, the attempt to capture Kansas by Missouri invasions in 1855 and 1856, the support of the Dred Scott decision and the Lecompton fraud in 1857, the repudiation of Douglas's Freeport heresy in 1858, to the demand for a congressional slave code for the Territories and the recognition of the doctrine of property in slaves. These last two points they had distinctly formulated in the first session of the Thirty-sixth Congress. On January 18, 1860, Senator Brown of Mississippi introduced into the Senate two resolutions, one asserting the nationality of slavery, the other that, when necessary, Congress should pass laws for its protection in the Territories. On February 2 Jefferson Davis introduced another series of resolutions intended to serve as a basis for the national Democratic platform, the central points of which were that the right to take and hold slaves in the Territories could neither be impaired nor annulled, and that it was the duty of Congress to supply any deficiency of laws for its protection. Perhaps even more significant than these formulated doctrines was the pro-slavery spirit manifested in the congressional debates. Two months were wasted in a parliamentary struggle to prevent the election of the Republican, John Sherman, as Speaker of the House of Representatives, because the Southern members charged that he had recommended an "abolition" book; during which time the most sensational and violent threats of disunion were made in both the House and the Senate, containing repeated declarations that they would never submit to the inauguration of a "Black Republican" President.

When the national Democratic convention met at Charleston, on April 23, 1860, there at once became evident the singular condition that the delegates from the free States were united and enthusiastic in their determination to secure the nomination of Douglas as the Democratic candidate for President, while the delegates from the slave States were equally united and determined upon forcing the acceptance of an extreme pro-slavery platform. All expectations of a compromise, all hope of coming to an understanding by juggling omissions or evasions in their declaration of party principles were quickly dissipated. The platform committee, after three days and nights of fruitless effort, presented two antagonistic reports. The majority report declared that neither Congress nor a territorial legislature could abolish or prohibit slavery in the Territories, and that it was the duty of the Federal government to protect it when necessary. To this doctrine the Northern members could not consent; but they were willing to adopt the ambiguous declaration that property rights in slaves were judicial in their character, and that they would abide the decisions of the Supreme Court on such questions.

The usual expedient of recommitting both reports brought no relief from the deadlock. A second majority and a second minority report exhibited the same irreconcilable divergence in slightly different language, and the words of mutual defiance exchanged in debating the first report rose to a parliamentary storm when the second came under discussion. On the seventh day the convention came to a vote, and, the Northern delegates being in the majority, the minority report was substituted for that of the majority of the committee by one hundred and sixty-five to one hundred and thirty-eight delegates—in other words, the Douglas platform was declared adopted. Upon this the delegates of the cotton States—Alabama, Mississippi, Louisiana, South Carolina, Florida, Texas, and Arkansas—withdrew from the convention. It soon appeared, however, that the Douglas delegates had achieved only a barren victory. Their majority could indeed adopt a platform, but, under the acknowledged two-thirds rule which governs Democratic national conventions, they had not sufficient votes to nominate their candidate. During the fifty-seven ballots taken, the Douglas men could muster only one hundred and fifty-two and one half votes of the two hundred and two necessary to a choice; and to prevent mere slow disintegration the convention adjourned on the tenth day, under a resolution to reassemble in Baltimore on June 18.

Nothing was gained, however, by the delay. In the interim, Jefferson Davis and nineteen other Southern leaders published an address commending the withdrawal of the cotton States delegates, and in a Senate debate Davis laid down the plain proposition, "We want nothing more than a simple declaration that negro slaves are property, and we want the recognition of the obligation of the Federal government to protect that property like all other."

Upon the reassembling of the Charleston convention at Baltimore, it underwent a second disruption on the fifth day; the Northern wing nominated Stephen A. Douglas of Illinois, and the Southern wing John C. Breckinridge of Kentucky as their respective candidates for President. In the meanwhile, also, regular and irregular delegates from some twenty-two States, representing fragments of the old Whig party, had convened at Baltimore on May 9 and nominated John Bell of Tennessee as their candidate for President, upon a platform ignoring the slavery issue and declaring that they would "recognize no other political principle than the Constitution of the country, the union of the States, and the enforcement of the laws."

In the long contest between slavery extension and slavery restriction which was now approaching its culmination the growing demands and increasing bitterness of the pro-slavery party had served in an equal degree to intensify the feelings and stimulate the efforts of the Republican party; and, remembering the encouraging opposition strength which the united vote of Frémont and Fillmore had shown in 1856, they felt encouraged to hope for possible success in 1860, since the Fillmore party had practically disappeared throughout the free States. When, therefore, the Charleston convention was rent asunder and adjourned on May 10 without making a nomination, the possibility of Republican victory seemed to have risen to probability. Such a feeling inspired the eager enthusiasm of the delegates to the Republican national convention which met, according to appointment, at Chicago on May 16.

A large, temporary wooden building, christened "The Wigwam," had been erected in which to hold its sessions, and it was estimated that ten thousand persons were assembled in it to witness the proceedings. William H. Seward of New York was recognized as the leading candidate, but Chase of Ohio, Cameron of Pennsylvania, Bates of Missouri, and several prominent Republicans from other States were known to have active and zealous followers. The name of Abraham Lincoln had also often been mentioned during his growing fame, and, fully a year before, an ardent Republican editor of Illinois had requested permission to announce him in his newspaper. Lincoln, however, discouraged such action at that time, answering him:

"As to the other matter you kindly mention, I must in candor say I do not think myself fit for the presidency. I certainly am flattered and gratified that some partial friends think of me in that connection; but I really think it best for our cause that no concerted effort, such as you suggest, should be made."

He had given an equally positive answer to an eager Ohio friend in the preceding July; but about Christmas 1859, an influential caucus of his strongest Illinois adherents made a personal request that he would permit them to use his name, and he gave his consent, not so much in any hope of becoming the nominee for President, as in possibly reaching the second place on the ticket; or at least of making such a showing of strength before the convention as would aid him in his future senatorial ambition at home, or perhaps carry him into the cabinet of the Republican President, should one succeed. He had not been eager to enter the lists, but once having agreed to do so, it was but natural that he should manifest a becoming interest, subject, however, now as always, to his inflexible rule of fair dealing and honorable faith to all his party friends.
