Here is Krauthammer's Audicity of Vanity and a quote:
" Every senator looks in the mirror and sees a president. Nonetheless, has there ever been a presidential nominee with a wider gap between his estimation of himself and the sum total of his lifetime achievements? "
Indeed. If Obama were a spark plug, measuring the gap between his achievements and his self-regard would take feeler gauge blades calibrated in Astronimical Units: those millions of miles from the Sun to Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. And several blades left over for the occasional orbit of visiting comets.
