[3] Lincoln, in collaboration with abolitionist Congressman Joshua R. Giddings, wrote a bill to abolish slavery in the District of Columbia with compensation for the owners, enforcement to capture fugitive slaves, and a popular vote on the matter.
[4] Realizing Clay was unlikely to win the presidency, Lincoln, who had pledged in 1846 to serve only one term in the House, supported General Zachary Taylor for the Whig nomination in the 1848 presidential election.
[7] This distant territory was a Democratic stronghold, and acceptance of the post would have effectively ended his legal and political career in Illinois, so he declined and resumed his law practice.
[10] The debate over the status of slavery in the territories exacerbated sectional tensions between the slave-holding South and the North, and the Compromise of 1850 failed to defuse the issue.
[15] Speaking in his Kentucky accent, with a very powerful voice,[16] he said the Kansas Act had a "declared indifference, but as I must think, a covert real zeal for the spread of slavery.
I hate it because it deprives our republican example of its just influence in the world ..."[17] Lincoln's attacks on the Kansas–Nebraska Act marked his return to political life.
[25] In part due to the ongoing violent political confrontations in the Kansas, opposition to the Kansas–Nebraska Act remained strong in Illinois and throughout the North.
The convention platform asserted that Congress had the right to regulate slavery in the territories and called for the immediate admission of Kansas as a free state.
[26] At the June 1856 Republican National Convention, Lincoln received significant support on the vice presidential ballot, though the party nominated a ticket of John C. Frémont and William Dayton.
Foner argues that Lincoln was a moderate in the middle, opposing slavery primarily because it violated the republicanism principles of the Founding Fathers, especially the equality of all men and democratic self-government as expressed in the Declaration of Independence.
[31] Lincoln argued, "The authors of the Declaration of Independence never intended 'to say all were equal in color, size, intellect, moral developments, or social capacity', but they 'did consider all men created equal—equal in certain inalienable rights, among which are life, liberty, and the pursuit of happiness'.
[33] Some eastern Republicans favored the reelection of Douglas for the Senate in 1858, since he had led the opposition to the Lecompton Constitution, which would have admitted Kansas as a slave state.
Lincoln warned that "The Slave Power" was threatening the values of republicanism, and accused Douglas of distorting the values of the Founding Fathers that all men are created equal, while Douglas emphasized his Freeport Doctrine, that local settlers were free to choose whether to allow slavery or not, and accused Lincoln of having joined the abolitionists.
[44] In the aftermath of the 1858 election, newspapers frequently mentioned Lincoln as a potential Republican presidential candidate in 1860, with William H. Seward, Salmon P. Chase, Edward Bates, and Simon Cameron looming as rivals for the nomination.
[46] On February 27, 1860, New York party leaders invited Lincoln to give a speech at Cooper Union to a group of powerful Republicans.
Lincoln insisted the moral foundation of the Republicans required opposition to slavery, and rejected any "groping for some middle ground between the right and the wrong".
[47] Despite his inelegant appearance—many in the audience thought him awkward and even ugly[48]—Lincoln demonstrated an intellectual leadership that brought him into the front ranks of the party and into contention for the Republican presidential nomination.
[55] In 1860 Lincoln described himself: "I am in height, six feet, four inches, nearly; lean in flesh, weighing, on an average, one hundred and eighty pounds; dark complexion, with coarse black hair, and gray eyes.
Lincoln's success depended on his campaign team, his reputation as a moderate on the slavery issue, and his strong support for Whiggish programs of internal improvements and the protective tariff.
[59] Most Republicans agreed with Lincoln that the North was the aggrieved party, as the Slave Power tightened its grasp on the national government with the Dred Scott decision and the presidency of James Buchanan.
Delegates from 11 slave states walked out of the Democratic convention, disagreeing with Douglas' position on popular sovereignty, and ultimately selected incumbent Vice President John C. Breckinridge as their candidate.
As Michael Martinez says: Lincoln and his political advisers manipulated his image and background....Sometimes he appeared as a straight-shooting, plain-talking, common-sense-wielding man of the people.
Even Lincoln's tall, gangly frame was used to good advantage during the campaign as many drawings and posters show the candidates sprinting past his vertically challenged rivals.
The goal was to demonstrate the superior power of "free labor", whereby a common farm boy could work his way to the top by his own efforts.
[65] The Republican Party's production of campaign literature dwarfed the combined opposition; a Chicago Tribune writer produced a pamphlet that detailed Lincoln's life, and sold 100,000 to 200,000 copies.
[71] On December 20, 1860, South Carolina took the lead by adopting an ordinance of secession; by February 1, 1861, Florida, Mississippi, Alabama, Georgia, Louisiana, and Texas followed.
[72] The upper South and border states (Delaware, Maryland, Virginia, North Carolina, Tennessee, Kentucky, Missouri, and Arkansas) listened to, but initially rejected, the secessionist appeal.
[77] Lincoln rejected the idea, saying, "I will suffer death before I consent ... to any concession or compromise which looks like buying the privilege to take possession of this government to which we have a constitutional right.
[79][80] A few weeks before the war, Lincoln sent a letter to every governor informing them Congress had passed a joint resolution to amend the Constitution.
The mystic chords of memory, stretching from every battlefield, and patriot grave, to every living heart and hearthstone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature.
