I think Hedges is one of the best commentators out there.

America the Illiterate
by Chris Hedges
Political leaders in our post-literate society no longer need to be competent, sincere or honest. They only need to appear to have these qualities. Most of all they need a story, a narrative. The reality of the narrative is irrelevant. It can be completely at odds with the facts. The consistency and emotional appeal of the story are paramount.
