Better or worse than talking to pictures?

From a column today by Georgie Anne Geyer:

…by all reports, President Bush is more convinced than ever of his righteousness.

Friends of his from Texas were shocked recently to find him nearly wild-eyed, thumping himself on the chest three times while he repeated “I am the president!” He also made it clear he was setting Iraq up so his successor could not get out of “our country’s destiny.”

Here’s the famous “crazy” section from The Final Days by Bob Woodward and Carl Bernstein:

On the Sequoia trip the night before, [Nixon’s son-in-law Edward] Cox said, the President had made it clear he was not going to quit…

Cox sounded distraught. He was worried about the President’s mental health. The President was not sleeping, and he had been drinking. The man couldn’t take it much longer, Cox said. The President had been acting irrationally…

“The President…” Cox began. His voice rose momentarily. “The President was up walking the halls last night, talking to pictures of former Presidents—giving speeches and talking to the pictures on the wall.”
