What this lacks is the demonstration that the ability to recognize sound judicial candidates also makes one a similar candidate.
If Ms. Miers has had a hand in selecting the judges nominated by the current administration, then she can recognize good judges. And I would have been happy with many, if not most of them, for the current opening. There is, however, the fact that there is more evidence of their expertise, experience,and committment than of her's, although, with the exception of Mr. Roberts, their nominations were for lesser positions.
This background of picking constructionist judges is certainly a point in her favor.
