And again he was blessed by the fact that McClellan was utterly incompetent
McClellan was not interested in winning the war. He sympathized withthe other side.
He ran against Lincoln in 1864 as the Democrats nominee.
"easily defeated the Democratic nominee, former General George B. McClellan, by a wide margin of 221-21 electoral votes, with 55% of the popular vote."
I don't know that that's true. I think he was a glory hound who wanted to lead victorious armies. But more than that, he didn't want to lose a battle, which paralyzed him. Even with Lee's battle plan in his hand, at Antietam, he was timid.
On the plus side, he did build the Army of the Potomac. The problem was that once he had them, he was afraid to do anything with them. The Peninsula Campaign was a brilliant idea, but once he landed the army, he delayed and delayed getting them moving until Lee was able to get his forces organized.
This I believe. He was considered awesome in his ability to organize and train the military, but terrible in his efforts to actually use it. I have long believed he was not so good at this because his heart really wasn't into it.
