Sounds as if the person you are describing is an autistic idiot-savant. If Miers has such hidden genius, she has been entirely successful in keeping it hidden. Do you have any evidence of it?
Ask Bush. He knows her.
Miers' undergrad degree was in math. I'm sorry, but if you switched the current Harvard Law class with the current SMU math majors, the SMU majors would pass Harvard Law almost uniformly and half of Harvard Law would flunk Abstract Algebra alone.
Now, I'm sure other people want to read purple prose, but lingustic skills are quite low on the intellectual food chain.
As my tagline says, I believe that I am qualified to be on the Supreme Court as much as anyone else. It is a political institution, it is not the private province of the lawyerly class. The SCOTUS is not like the Fed, an institution created by Congress and subcontracted to do its duty. I understand strict constructionism and the average person can. If I am to have any right to criticize moronic SCOTUS decisions, then those who decide such things should not be members of a special priestly caste.
