Can you guess what it is?

Is it having 9/11 on his watch, especially after disregarding Richard Clarke's warnings about al Qaeda?

Is it lying to American people to invade and occupy a country that posed no threat to us?

Is it the rendition and torturing of detainees?

Is it the trillions of dollars lost in the sands of the middle east?

Is it the collapse of the economy on his watch and due to his neglect?

Is it the thousands of people left dead and homeless on the Gulf Coast because the warnings about the levees were ignored and the federal response was inexcusably late and poorly handled?

Amazingly enough, none of that is what Bush considers the worst moment of his presidency. His worst moment is below the jump:

Seriously.

George Bush, still thin-skinned as ever, is still stewing of Kanye West:

MATT LAUER: You remember what he said?
PRESIDENT GEORGE W. BUSH: Yes, I do. He called me a racist.
MATT LAUER: Well, what he said, "George Bush doesn't care about black people."
PRESIDENT GEORGE W. BUSH: That's -- "he's a racist." And I didn't appreciate it then. I don't appreciate it now. It's one thing to say, "I don't appreciate the way he's handled his business." It's another thing to say, "This man's a racist." I resent it, it's not true, and it was one of the most disgusting moments in my Presidency
MATT LAUER: This from the book. "Five years later I can barely write those words without feeling disgust." You go on. "I faced a lot of criticism as President. I didn't like hearing people claim that I lied about Iraq's weapons of mass destruction or cut taxes to benefit the rich. But the suggestion that I was racist because of the response to Katrina represented an all time low."
PRESIDENT GEORGE W. BUSH: Yeah. I still feel that way as you read those words. I felt 'em when I heard 'em, felt 'em when I wrote 'em and I felt 'em when I'm listening to 'em.
MATT LAUER: You say you told Laura at the time it was the worst moment of your Presidency?
PRESIDENT GEORGE W. BUSH: Yes. My record was strong I felt when it came to race relations and giving people a chance. And-- it was a disgusting moment.

Amazing, isn't it? How much blood and treasure were lost on George Bush's watch and that doesn't impact him as much as some recording artist emotionally acting out during a fundraiser?
