You really need to give it up. Leadership was published in October of 2002, eight years after Reagan announced he had Alzheimer's. Do you actually think he chose this book to be sold in his library's gift shop? Do you think he even read it or was aware that it existed in October of 2002? Give it a rest already, you were wrong, you've been proven wrong on multiple threads and it's beyond the point of ridiculous.
You'll have to show me where I was proven wrong. I'll be back to check it out.
I know it just about kills all you haters that Giuliani was so well thought of that he was appointed by Reagan as the #3 man at DOJ and his book given such a prominent display on the Reagan Library web site, but really, it's a fact you'll just have to come to terms with.
