Bork's opinion regarding this nomination are genuine and sincere, as is usually the case when we hear from him. His tendency to be honest regarding his beliefs, is the primary reason he was Borked in the first place.
He believes David Brooks discredited Miers. He couldn't do it himself, so he resorts to a NYTimes staffer to do the work for him.
Talk about ugly!
Bork didn't attack Roberts because Roberts was the most brilliant witness to ever testify before the judiciary committee.
