With hindsight, I voted no because Lincoln would have wanted it that way. If Davis was going to be hanged then Robert E. Lee should have followed him.
Ironically I was at Fort Monroe the other day - the place where Davis was imprisoned.
They never even committed a crime in the first place. Of course you can't hang an innocent man.
And the one thing I've always wondered if Lincoln said secession was invalid and the southern states never left the union then why were they kicked out at the end of the war and then had to be readmitted to the Union? Also, why were legislators who opposed ratification of the 14th amendment conveniently "removed" from office and replaced by legislators who didn't oppose ratification, like what occurred in Oregon.
