You've forgotten the "Corwin Amendment" which Lincoln supported and which was passed by both houses of congress and which was ratified by five Northern states.

It's still possible to ratify it because it does not have a sunset provision like later amendments did.

So we could theoretically get slavery back.

Hmmm.... interesting!

Thanks for pointing that out. Adds another ingredient into the mix.
