Why would Bush want to put a moderate in there and get the same thing he has been B*TCHING about for 4 years? Judges legislating from the bench!
See doc30's post in #17. The tacit assumption of Morris' prediction is that Mr. Bush is not really a conservative, but pays lip service only to conservative values. There are solid rebuttals to this, but overall, I agree with doc30 and that assumption. We could each go down our respective lists of conservative versus non-conservative, but it would serve no purpose, other than an argument.
To answer your question, I would ask you one: why would Bush want to put a moderate in the AG position?
