I don't see how you can say that based on just two years on the Texas Supreme Court. Besides, your statement that he has "consistently upheld abortion rights" ignores that as a Justice on the Texas Supreme Court, he had no choice but to uphold abortion rights. The Texas Supreme Court does not decide whether there is a constitutional right to abortion in the US Supreme Court. He simply takes that as given by the US Supreme Court.
As I've said before, I am not arguing that Gonzales is a conservative. I am simply pointing out that you can't tell based on a 2 year record on the Texas Supreme Court. But I am sure that Bush knows whether he is a conservative. And if he appoints him, then I am certain it will be because he knows Gonzales better that you.
