Oh he should. I just doubt it will work.

"You certainly missed the point of my comment though, which was about Lincoln's application of the same principle within his own Party"

But that was not the point of the Lincoln speech. More important, Lincoln was supposed to be the candidate of the moderate wing of the republicans. And indeed most of his coalition management troubles came from so called radical republicans.

And regarding the south, Lincolns willingness to compromise hadn't worked from the start of the civil war. I really doubt it would have worked better in post war era (His power over the republicans would have avoided the impeachment, though).

 "  And no, I won't stop pointing out when you don't engage in proper debate and have an abysmal attitude that is getting quite annoying"

The problem is, you always claim to misunderstood and can' stand to be contradicted in anything.
