Gentlemen,
I'd really like to know from what historical works you are getting your facts on Lincoln. Do you just make them up?
Lincoln ran on the express platform that as President, he would not in any manner try to abolish slavery in the states in which it then existed. He stated this over and over, and he meant it. Where he differed radically from the southern viewpoint was that he would not let slavery be extended into the new territories. This infuriated the southern slave owners, since they wanted to extend slavery into all of the new states that would be created out of the territories, including Nebraska, New Mexico and even California.
The main fear of the South was that if the new territories came in as free states, then a super majority of free states would be created in Congress, thereby giving Congress enough votes to amend the Constitution to abolish slavery everywhere. Not likely, since most of the Midwestern states didn't give a rat's butt about slavery. Nor did most folks in Pennsylvania or New York.
Lincolns wife, Mary Todd, was a wealthy woman from huge plantation in Kentucky (a slave state that stayed in the Union). Her family owned lots of slaves there.
Lincoln's worst nightmare was a Civil War. But, he was willing to have one in order to keep the Union together by not letting the Southern states secede. The minute he was elected, the deep south states started to secede, since their legislatures were totally controlled by rich slave owners. The border states did not. They stayed in, expressing sentiment to stay in the Union and try to reach a peaceful solution.
Lincoln did not sign the Emancipation Proclamation until more than two years after he was in office. And he had real doubts about doing so. He delayed signing it for months on end. He did so only because he was worried about getting re-elected, and because the War (despite Gettysburg) had no end in sight after years of butchery.
The Emancipation Proclamation did not free all of the slaves in the country. It expressly states that it only applied to the "states in rebellion". Accordingly, it did not apply to (and wasn't intended to apply to) any slave state that had remained in the Union, principally Kentucky, Maryland, and Delaware.
