You are mistaking desperate attempts to avoid a war with the politicians actual positions.
Lincoln sought many compromises to save the Union. Acceptance of tis Democrat measure being one of them.
HOWEVER, that does not change his fundamental position, nor the fundamental positions of the treasonous Breckenridges position.
“Outgoing President James Buchanan endorsed the Corwin Amendment by taking the unprecedented step of signing it.[15] His signature on the Congressional joint resolution was unnecessary, as the President has no formal role in the constitutional amendment process.[16]
Abraham Lincoln, in his first inaugural address on March 4, said of the Corwin Amendment:[17]
I understand a proposed amendment to the Constitution—which amendment, however, I have not seen—has passed Congress, to the effect that the Federal Government shall never interfere with the domestic institutions of the States, including that of persons held to service ... holding such a provision to now be implied constitutional law, I have no objection to its being made express and irrevocable.
Just weeks prior to the outbreak of the Civil War, Lincoln sent a letter to each state’s governor transmitting the proposed amendment,[18] noting that Buchanan had approved it.[19]”
I am pointing out that Lincoln was willing to sell all the slaves down the river to keep economic and political control of the Southern states.
Therefore the primary issue of the war was not concern about slaves, it was concern about keeping the South's economic system under the control of Washington DC, where the more numerous Northern advantage in Congress could keep Southern money flowing through New York and Washington DC hands.
Lincoln sought many compromises to save the Union. Acceptance of tis Democrat measure being one of them.
It's primary advocates were Republican Thomas Corwin from Ohio, and Republican William Seward from New York. There is even some circumstantial evidence that Lincoln even initiated it. Seward was Lincoln's Secretary of State.
Just weeks prior to the outbreak of the Civil War,
Interesting statement. Just how did Lincoln happen to know they were "Just weeks prior to the outbreak of the Civil War..."? What made anyone believe that war was weeks away?
You are aware that Lincoln sent a battle fleet to Charleston to attack the Confederates there, and perhaps this is how people knew war was "Just weeks prior to the outbreak of the Civil War..." ?
Lincoln's cabinet certainly made it clear that if sent those warships, it would cause a war. The vast majority of them were completely against Lincoln doing this, because they said it would trigger a war.
Lincoln sent a letter to each state’s governor transmitting the proposed amendment,[18] noting that Buchanan had approved it."
Yes he did, and this is an unusual step because the president plays no role in the passage of constitutional amendments. One can only surmise his letter was intended to make the governors aware that he was backing this amendment, because if he opposed it, he would hardly send a letter to notify them of it, or if he did, it would have voiced his opposition.
