The truthiness hurts | Salon.com:
For Colbert, the punch line is just the addendum. The joke is in the setup. The meat of his act is not in his barbs but his character -- the dry idiot, "Stephen Colbert," God-fearing pitchman, patriotic American, red-blooded pundit and champion of "truthiness." "I'm a simple man with a simple mind," the deadpan Colbert announced at the dinner. "I hold a simple set of beliefs that I live by. Number one, I believe in America. I believe it exists. My gut tells me I live there."
Then he turned to the president of the United States, who sat tight-lipped just a few feet away. "I stand by this man. I stand by this man because he stands for things. Not only for things, he stands on things. Things like aircraft carriers and rubble and recently flooded city squares. And that sends a strong message, that no matter what happens to America, she will always rebound -- with the most powerfully staged photo ops in the world."
It was Colbert's crowning moment. His imitation of the quintessential GOP talking head -- Bill O'Reilly meets Scott McClellan -- uncovered the inner workings of the ever-cheapening discourse that passes for political debate. He reversed and flattened the meaning of the words he spoke. It's a tactic that cultural critic Greil Marcus once called the "critical negation that would make it self-evident to everyone that the world is not as it seems." Colbert's jokes attacked not just Bush's policies, but the whole drama and language of American politics, the phony demonstration of strength, unity and vision. "The greatest thing about this man is he's steady," Colbert continued, in a nod to George W. Bush. "You know where he stands. He believes the same thing Wednesday that he believed on Monday, no matter what happened Tuesday."
