In fact, bush promised us a scalia or thomas when he would be appointing judges.
Not an unknown along with a wink and a nod.
How TF do you know that she isn't a Scalia or a Thomas? Are you Miss Cleo?
I don't think the President cares, or should care, if the nominee is "unknown" to you. All that matters is if the nominee can do the job, and being "unknown" to you has no relevance in this regard since by your own admission you know nothing and it is not your decision.
People need to get a grip and listen to themselves. Conservatives throwing temper tantrums and having hissy fits in the complete absence of wrong on the part of the President.
Bush promised us a strict constructionist, and you have yet to find out if she would be a Scalia or a Thomas, heck we really didnt know if Scalia or Thomas would be what they are today until they got put on the bench and got some time.
