This is a good article indeed. It's interesting that Fox News is already describing how the book "slams" President Obama. I wonder whether the book, read as a whole, takes that tone, or whether this is just Newscorp being Newscorp. Certainly that article suggests he had a worse time under President Obama than under Bush, but I don't read it as categorically criticizing Obama (not surprising, since presumably if he found his job so unworkable under Obama he would have resigned). His harshest comments seem to be about Congress.
