This unselfish devotion to principle was a great source of his power. Placing himself at the head of those who opposed the extension of, and who believed in the moral wrong of slavery, he entered upon his great mission with a singleness of purpose, an eloquence and power, which made him as the advocate of freedom, the most effective and influential speaker who ever addressed the American people.
He brought to the tremendous struggle between freedom and slavery physical strength and endurance almost superhuman. Notwithstanding his modesty and the absence of all self-assertion, when we review the conflict from 1854 to 1865, when the struggle closed by the adoption of the constitutional amendment abolishing and prohibiting slavery forever throughout the republic, it is clear that Lincoln's speeches and writings did more to accomplish this result than any other agency.
Following the repeal of the Missouri Compromise came the Kansas struggle, and the organization of a great party to resist the encroachments and aggressions of slavery. The people instinctively found the leader of such a party in Lincoln.
Looking over the whole ground, with the sagacity which marked his far-seeing mind, he saw that the basis upon which to build were the grand principles of the Declaration of Independence. This foundation was broad enough to include old-fashioned Democrats who sympathized with Jefferson in his hatred of slavery; Whigs who had learned their love of liberty from the utterances of the Adamses and Channings, and the earlier speeches of Webster; and anti-slavery men, who recognized Chase and Sumner as their leaders.
He now addressed himself to the work of consolidating out of all these elements a party, the distinctive characteristics of which should be the full recognition of the principles of the Declaration of Independence and hostility to the extension of Slavery. This was the party which in 1856 gave John C. Fremont 114 electoral votes for President, and in 1860, elected Lincoln to the executive chair.
In the midsummer of 1858, Senator Douglas, whose term approached its close, came home to canvass for re-election. It was in the midst of the Kansas struggle, and although he had broken with the administration of Buchanan, because he resisted the admission of Kansas into the Union, under the fraudulent Lecompton Constitution, and insisted that the people of that State, should enjoy the right by a fair vote, of deciding upon the character of their Constitution,[5] yet the people of Illinois did not forget that he was chiefly responsible for the repeal of the Missouri Compromise, and that he had indorsed the Dred Scott decision. On the 17th of June, 1858, the Republican State Convention of Illinois met and by acclamation nominated Mr. Lincoln for the Senate. He was unquestionably more indebted to Douglas for his greatness than to any other person.
