Impervious

Bill Saletan posits that Bush doesn't have a learning disability as much as he has a reality disability.

...Bush's notion of credibility turns out to be dangerously unhinged. The only words and deeds that have to match are his. No correspondence to reality is required. Bush can say today what he said yesterday, and do today what he promised yesterday, even if nothing he believes about the rest of the world is true.

Outside Bush's head, his statements keep crashing into reality...

Inside Bush's head, however, all is peaceful.

Saletan skillfully deconstructs a number of Bush's responses -- it would be inaccurate to call them "answers" -- to last night's questions.

The inescapable conclusion Saletan offers is that Bush is "impervious to evidence." Events swirl, the world changes, new realities are formed. But through it all our hapless, happy-go-lucky "leader" trots out time tested platitudes and stock phrases. Whether his banal remarks provide insight into the past or light the way forward really doesn't matter. As long as there is an appearance of constancy the great leader theory will persist.

In this, significant portions of the American electorate remain impervious to evidence.
