Why can't Bush talk about Iraq without a cheat sheet?

I'm watching PBS' "The News Hour" from last night and Bush is AGAIN using a cheat sheet when talking about Iraq. EVERY SINGLE TIME this man does a public event and speak abouts the details of Iraq and the details of the situation in Iraq, and the details of his criticism of John Kerry's position, HE LOOKS DOWN AT HIS NOTES. Seriously, check out it - at every town meeting he can't speak off the cuff without a cheat sheet. The man literally has no idea what he's saying.
