[Sherman Logan]

It was passed during the Buchanan administration, when the proslavery and eventual secessionists were still in Congress

Only partially correct.

The Deep South states had already all seceded, although all the Upper South and Border states were still sitting in Congress.

It was ratified by OH and MD, and perhaps by IL.

[Repeal 16-17]

It was ratified by OH and MD, and perhaps by IL.

Ohio rescinded its ratification in 1864. Maryland, this April, rescinded its ratification. So depending on the validity of the rescissions and Illinois's ratification, the Corwin Amendment might currently have zero ratifications.

> Essentially, the Crittenden Compromise sought to alleviate all concerns of the Southern states. Four states had already left the Union when it was proposed, but Crittenden hoped the compromise would lure them back. Crittenden thought he could muster support from both South and North and avert either a split of the nation or a civil war. The major problem with the plan was that it called for a complete compromise [sic] by the Republicans with virtually no concessions on the part of the South.

IOW it wasn’t a compromise, it was a repudiation of the Republican platform of 1860 before he was even sworn in, and Lincoln rightly rejected it. If the Demagogic Party tried it today, they’d include hate speech provisions to prohibit criticism of slavery.
