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?
I've seen this game you play too many times already.
