Name the America-Hater

Since the last couple days have been set aside for the GOP to stay "waist deep in big sandy" who authored and spoke this anti-war screed?

I shall be fully convinced of what I more than suspect already—that he is deeply conscious of being in the wrong; that he feels the blood of this war, like the blood of Abel, is crying to Heaven against him . . ., and trusting to escape scrutiny by fixing the public gaze upon the exceeding brightness of military glory, that attractive rainbow that rises in showers of blood—that serpent's eye that charms to destroy, ... he now finds himself he knows not where....

As I have before said, he knows not where he is. He is a bewildered, confounded, and miserably perplexed man. God grant he may be able to show there is not something about his conscience more painful than all his mental perplexity.
