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.
I think you're missing something, though. We're not afraid that Bush is trying to find a Scalia, and messing up without our help. Many of us are afraid that he doesn't give a d--n about picking a Scalia, and is purposely picking justices who will prove to be "moderates". It's not that we don't trust him to get it right; we don't even trust his intentions.
Please, you are tone deaf. Bush is feeling the heat. You are the minority opinion in this fight.
