Lincoln was a man, a railroad lawyer and sometimes bum, with a super sized ego, that knew no bounds.
The only problem with booth plan was he didn't do it soon enough, and allow the democrats and copperheads to win the 64 election, thus resulting in a negotiated peace.
BTW that is why Powell reminds me so much of McClellan, he was the democratic candidate with a secret plan to end the war.
As a Southerner, Texan, we were taught to have great respect for Lincoln. His picture was usually displayed as much as Washington's. We celebrated his birthday, learned about using the back of his shovel for a slate, etc. Some people think Southerners were taught he was the devil incarnate, I don't know about other states - but not in Texas. That is just another bit of either revisionist history or wishful thinking.
