Ideas for a book gift for conservative relative?

[imenja]

I'd like to give a Republican relative of mine a book as a gift for Christmas. He votes Republican, but I believe he has an essentially good heart. When I ask him about issues, he doesn't support hard right wing positions. I believe he votes Republican because of his family background, simply because he always has.
I'd like to find a book that critiques the Bush administration or neo-conservatism from the inside: a book by a conservative that a Republican won't immediately dismiss as left-wing propaganda. It shouldn't seem inflammatory. I basically want to introduce him to a critique in a gradual, perhaps even covert, fashion so that he will actually read the book. Any ideas?
