It is clear what the Corwin amendment actually said. It is clear that Lincoln actually urged it's passage.
Your attempts to spin what is the clear truth are now just a source of amusement to me.
Corwin merely said what was already Federal policy -- slavery was a states' issue and would not be abolished from Washington, DC.
DiogenesLamp: "It is clear that Lincoln actually urged it's passage."
But there was no "urge" to it, Lincoln merely said he did not object to something that was already long-standing policy.
We know what happened when Lincoln did fully urge the 13th Amendment (abolition) -- it was soon ratified.
By stark contrast, Corwin died from lack of Lincoln's support.
So why do you keep lying about it?
