Okay, but at least they held some important Judicial post prior to being nominated. Rehnquist clerked for a Justice, and he was #2 at the Justice Department. The most Miers can claim is that she was president of the Texas Bar and the President's personal lawyer. That's hardly on the same level.
You have something against the private sector? Do you think only those who have suckled at the states teat are capable of reading and understanding the constitution? I've spent my entire adult life in the private sector. Met a lot of very smart and capable folks. I'm not buying what you and a bunch of others are selling. Constitutional law is not that hard. When the constitution says the people have a right to keep and bear arms, that's exactly what it means.
