You are right, we do not know how she will turn out.
But we do know she is not a nominee in the mold of Thomas or Scalia.
And what was Thomas resume when he was nominated? Thiner than that of a hundred other possibilities.
How many times does the National Review article, from 1991, which states that Clarence Thomas was "an unknown, more in the mold of David Souter" have to be posted?
Clarence Thomas was an affirmative action pick, and, like Miers, was characterized by GHWBush as "the most qualified candidate available." That description was derided by liberal and conservative media.
Clarence Thomas was as much a cipher as Harriett Miers.
"But we do know she is not a nominee in the mold of Thomas or Scalia."
Actually no, we don't know that. See my previous.
