There ought to be a rule for SCOTUS.
After 10 years serving as a Justice, that a president can replace him/her with a new appointee, but only if the majority of Americans wish for it, via a petition that collects at least 20 million votes (verified and only one vote per person) to replace or just outright FIRE him/her.
When you don’t represent the wishes of the people that sent you there, then you should be sent out the door.
Use Obama as you test case, and see if you really want to
give him that kind of power.
Supreme court justices aren’t there to represent the wishes of the people who sent them there, they are there to interpret the law.
