Papal/Presidential infallibility

I can laughingly ignore the concept/doctrine of papal infallability. But the concept and(according to this article) doctrine of presidential infallability is very troubling. What am I to think and how am I to act though when the large volume of alarmist opinion on the present administration's sins has had no effect? Everything in this piece basically makes sense to me, but I despair of Bush and his cronies ever being brought to account for their abuse of power.
