The Mahablog tries to explain the mind of the Current Resident:

Today many wonder how the President can seem so confident we are “winning” in Iraq. Is he truly delusional, or is he just trying to happy-face his way out of trouble? All I know is that he cares passionately about Iraq. You can argue about the purity of his motives but not, I think, about the intensity of his concern. No other subject gets him more worked up at a podium. Last week he made a point of defending his Iraq policy, even as the Republican Party would rather the public not be reminded.
