George Bush to American Public: Drop Dead
A slow learner is someone who, among other things, refuses to learn from his mistakes and blames others for them.
In this instance his mistake is the Mess in Mesopotamia and the subject of his blame is Al Qaeda, which had zero presence there until the war came a cropper.
A slow learner also refuses to acknowledge the admonitions of others to try to learn from his mistakes.
In this instance the drubbing voters gave him a mere three weeks ago when they sent him the message that they werenâ€™t buying his Al Qaeda BS and wanted him to get the U.S. the heck out of Iraq as soon as reasonably possible.
