In my years of court watching I have never even seen a "conservative" nominated, including Bork. They all were originalists and textualists and the left identifies them as conservative.
The left nomiates jurists that believe the constitution "grows" as we make progress as a society, in that growth they find penumbras that they say support their decisions, though no text actually exists to support that contention.
Once a justice makes it they have a lifetime appointment and can be themselves, not under anyone. It is a fact of human nature that humans often get softer and reflective the nearer they get to the end of life. I hope this trend of younger justices doesn't give them longer to become liberal...
What does a conservative who is not an originality or textualist look like?
