This statement from his latest column tells you pretty much all you need to know about Joseph Farah:
I think Sarah Palin should sue the daylights out of Joe McGinniss and his publisher for their reckless disregard for the truth they showed in his new book –which, for the purpose of this column, shall remain nameless.
No, I have not read the book, nor do I intend to read it.
Then you have no idea what is true and what is not. I don’t either. And I also don’t intend to read it. I have no idea which claims in it are true and which are false. But I’ll make this prediction. Despite her lawyer’s threats, there isn’t a chance in hell that Palin is going to sue McGinnis, for one simple reason: It would open her up to discovery and subpoenas. It’ll never happen.
