And still more cockamamie nonsense.
There's no record to suggest Corwin was "orchestrated" by Lincoln, "offered" to Confederate states or "rejected" by them.
The record clearly does show Corwin passed under and signed by President Buchanan, directed towards & accepted by Union slave-states like Kentucky & Maryland.
It also shows that Senator Davis himself, before January 21, 1861 when he left the Senate, worked on his version of Corwin's idea.
Indeed, no secessionist was ever recording as promising that if the Union simply dropped Morrill, or spent more money in the South, then they'd be happy to return.
That should tell us all we need to know about what secessionists said was their biggest concern: slavery.
