And, in all fairness, you also realize that people write politically motivated books all the time that have no basis in fact?
This was more than a letter fawning over the President. It *specifically* addressed the "Faith-Based Initiatives" he later criticized in his book.
I do quite understand what you're saying, but this wasn't a "Hey, it was nice working for you" type of letter. He was specific in what he said, and he later contradicted it. If he wanted to maintain credibility for a book later on to tell "the real story", he certainly didn't help himself by being that specific in his letter.
And again, the core of my problem with this whole thing - it's NOT about Bush. It's about Rove. As I said, Bush should be called out on Rove, one of his staffers, getting out of line (if indeed the book is even accurate, that is), but that's about all the blame he should take in this, as far as I can see from what everyone's describing the book as talking about (since I've not read it, nor do I plan to).
