To become a judge of the magnitude of the Supreme Court, a judge has to be his own person for some long time. Nobody knows who will become President 30 or 40 years down the road. The judge is who he is, and just happens to fit a particular president better than some other president.
The most important thing is this. Supreme Court judges exist for helping to balance the government corporation. If a judge's ruling injures you, or deprives you of your freedom in some way, take it to Federal District Court in common law, where the judge is only a referee, and the jury (the real judge) decides whether or not a law applies to you.
Be careful to allow your half of the jury people that seem to be on your side when you question them ahead of time.
