Order (or go out and buy) Unfit for Command. It's an easy and informative read (well documented) of about 200 pages.
Bought it last night at Hastings for $16.88.It is a must read book. I stayed up until 2AM, so will finish it today.
If everyone in the swing states would thoughtfully read this book, I think that Bush would easily take those states. The book is very well documented.
