Of course we always knew it was about power, not virtue, but Pat Robertson's support of Giuliani tells us something even more remarkable.
Robertson can't believe in the God he preaches about. In particular, he clearly doesn't believe in a personal and judgmental deity who consigns sinners to eternal damnation.
If he did believe in that monster, he wouldn't touch Giuliani with a 10 foot pole.
To a reasonable approximation, it appears Robertson doesn't believe in his God.
