It has mostly been confinced to the right thus far (see Charles Krauthammer, our own John Tabin), but in this morning’s Washington Post, Dana Milbank dubs Obama the “presumptuous nominee,” and catalogues how he is acting as if he is already president. While Americans like to see confidence in their politicians, I think this is the one narrative that has the potential to hurt Obama, because his hubris is inversely proportional to his experience.
