That was a funny clip.
I hadn't heard of the decider stuff either, but I found
this article.
Pressed to respond to critics who say he is ignoring the advice of respected former military commanders, Bush vigorously stood by Rumsfeld.
"I listen to all voices, but mine is the final decision," he said. "And Don Rumsfeld is doing a fine job. He's not only transforming the military, he's fighting a war on terror. He's helping us fight a war on terror. I have strong confidence in Don Rumsfeld.
"I hear the voices, and I read the front page, and I know the speculation. But I'm the decider, and I decide what is best. And what's best is for Don Rumsfeld to remain as the secretary of defense."
Frankly I would've jumped on the hearing voices bit m'self, but to each his own.
