Okay. Just seeking clarification, cause the amendment you described sounded very similar to The Lincoln's.
Actually the proposed 13th Amendment resembles the one that was part of the Crittenden Compromise:
Crittenden Compromise
"...and no amendment will be made to the Constitution which shall authorize or give to Congress any power to abolish or interfere with slavery in any of the States by whose laws it is, or may be, allowed or permitted"
13th Amendment passed by Congress:
"No amendment shall be made to the Constitution which will authorize or give to Congress the power to abolish or interfere, within any State, with the domestic institutions thereof, including that of persons held to labor or service by the laws of said State."
That was a Democrat proposal, if memory serves.
