The president’s problem isn’t that he is too visible; it’s the lack of content in what he says when he keeps showing up on the tube. Obama can seem a mite too impressed with his own aura, as if his presence on the stage is the Answer. There is, at times, a self-referential (even self-reverential) tone in his big speeches. They are heavily salted with the words “I” and “my.” (He used the former 11 times in the first few paragraphs of his address to the U.N. last week.) Obama is a historic figure, but that is the beginning, not the end, of the story…

He did it again in that U.N. speech. The delegates wanted to know what the president was going to do about Israel and the Palestinian territories. He answered by telling them what his predecessor had failed to do. This was effective for his first month or two. Now it is starting to sound more like an excuse than an explanation…

Obama seems to think he’ll get credit for the breathtaking scope of his ambition. But unless he sees results, it will have the opposite effect—diluting his clout, exhausting his allies, and emboldening his enemies.
