The fact that one pundit-who has no power to impact the executive's decisions-critiques a choice that the vast majority of conservative Republicans would have a problem with anyway does not absolve him of responsibility.
If Miers is such an inspired choice than she would have had the overwhelming-if not uniform-support of conservatives in this country.
The fact that there is an acrimonious debate occurring at the moment is evidence that she isn't the brilliant selection that some people are claiming.
There was the same acrimonious debate over John Roberts, though there were fewer participants.
Anyone who thinks that Roberts was not a brilliant choice is blind.
