We've already covered that. Lincoln had no legal power to do such a thing. If states have a right to leave, Lincoln could not tell them "no." If States have no right to leave, Lincoln cannot tell them "Yes."
It is an abuse of power on the very face of it.
It doesn't matter what "The Deal" was, Lincoln did not have the constitutional authority to make such a Deal.
Either the matter of states leaving was an affair for the entire government, and especially the Congress, or it was entirely a matter of the States being free to do as they wished.
From a constitutional standpoint, I don't see where Lincoln has any power to "Make a Deal" over the issue.
Yet again you jabber anti-factual nonsense, word-salad meaning nothing.
And regardless of how often you repeat such gibberish, it's still gibberish, and makes no sense.
So why do you do it?
