If you don’t think there will be a difference between Hillary/Obama picks for the court and McCain picks you are being silly. I think it’s just hyperbole on your part. You’ve got to see that even if McCain makes “moderate” choices for the court that is better than straight, out and out left-wing-activist choices.
McCain is a backstabbing, egotistical old man who cannot be trusted. I don't want him anywhere near the Oval Office. If you believe he'll make "moderate" choices for the court, you are treating McCain as your personal Rorshach test. Any judicial choices he might make he would first vet with his liberal buddies in the Senate, both to ensure passage, and most importantly, to ensure favorable coverage with the media.
