Miers managed to head the Bar in Texas; quite an accomplishment for a lady in a then male-dominated field.
Ann uses blonde hair, long legs and crude attacks to become a media starlet. Big deal. She couldn't carry Miers's legal pad.
And Meirs couldn't get on a TV talk show unless she was nominated to the Supreme Court or something crazy like that. What's your point? They each do what they do, and apparently, pretty well. So they are not interchangeable. Ann is popular because she says the things we all wish more conservatives would say. The legs are a bonus.
