Please provide evidence for this. There was no attempt by the Federal government to force, or even influence, slave states to abolish slavery prior to the 1860 election.
The issue in that election was entirely one of whether:
A. Slavery would be prohibited in the territories (Lincoln).
B. Slavery would be allowed to expand into the territories, with a federal slave code enforced to protect it (Bell and Breckenridge).
C. To allow slavery or not in a territory would be left up to the people of that territory (Douglas).
Abolishing slavery in states wasn't even discussed.
You are confusing me - first you said slavery was the ONLY issue in the civil war, now you are saying it was not an issue at all
Please tell me what started the civil war, then... because I am confused now
