Frank Rich: Why Dick Cheney Cracked Up

In the days since Dick Cheney lost it on CNN, our nation’s armchair shrinks have had a blast. The vice president who boasted of “enormous successes” in Iraq and barked “hogwash” at the congenitally mild Wolf Blitzer has been roundly judged delusional, pathologically dishonest or just plain nuts. But what else is new? We identified those diagnoses long ago.

The more intriguing question is what ignited this particularly violent public flare-up.The answer can be found in the timing of the CNN interview, which was conducted the day after the start of the perjury trial of Mr. Cheney’s former top aide, Scooter Libby. The vice president’s on-camera crackup reflected his understandable fear that a White House cover-up was crumbling. He knew that sworn testimony in a Washington courtroom would reveal still more sordid details about how the administration lied to take the country into war in Iraq.
