[DiogenesLamp]

Read Lincoln's first inaugural address. He says it quite explicitly.

Lincoln supported an amendment to protect slavery.

Here. Let this black Boston College law professor explain it to you.

Here is the original proposed 13th amendment.

"No amendment shall be made to the Constitution which will authorize or give to Congress 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.

Declaring that he had “no objection” isn’t the same as supporting it. It was a mistake on Lincoln’s part as he soon discovered by the south’s treacherous behavior.

Lincoln supported an amendment to protect slavery.

Try this: Lincoln stated that he had no problem with the Corwin Ammendment being made express and irrevocable. The Corwin Ammendment plainly states that Slavery would thenceforth be a States Rights issue and could not be interfered with by Congress. Lincoln sent out letters to every state Governor, north and south, making sure that they all knew of the proposed Ammendment and his stance on it. He did that in a last ditch effort to avert war. In no way, shape, or form did Lincoln say or suggest that Slavery be made “express and irrevocable”.

DiogenesLamp on Corwin: "Read Lincoln's first inaugural address.
He says it quite explicitly.
Lincoln supported an amendment to protect slavery."

DiogenesLamp has a huge talent for putting his own words into mouths of historical figures.
On the proposed Corwin amendment, some key points:

1. It should be called the Jefferson Davis/Corwin amendment, since Senator Davis first proposed it in December 1860 as a way to prevent states from seceding.

2. It passed with Democrat support, signed by Democrat President Buchanan.

3. Lincoln did not sign it and clearly explained in his inaugural he did not object because he believed Davis/Corwin merely made explicit what the Constitution already implied.

4. Proposed by Ohioan Rep. Corwin, Davis/Corwin was only ratified by Ohio (which soon rescinded ratification), Kentucky, Maryland & Rhode Island.

5. For about a year Lincoln kept open the possibility of ending the war without emancipating slaves, but by summer of 1862 that ended in Lincoln's mind and so did any remote possibility for ratification of Davis/Corwin.
