This is the first thing I have heard that makes me feel a bit better about Miers. I have the greatest respect for Scalia. If she's ok with him, that means a lot.
I think what he's saying is accurate, but it doesn't necessarily reflect on Miers. As a general statement, he's right--people criticizing Miers for her lack of judicial experience are off-base. This doesn't mean that she's a good pick, otherwise.
