District Court judges are simply not the same as Supreme Court judges. Besides the Supreme Court has NO ADMINISTRATIVE control over the lower courts!
Congress has retained FULL control over the details of administering the courts ~ providing courthouses, providing heat in the winter, cooling in the summer, and turning on the lights and buying them supplies.
Disposing of bad judges in those courts is a good idea.
You need to think about the consequences of what you are saying right now. What you are saying is a blatant violation of our constitution:
Article III, Section 1
The judges, both of the supreme and inferior courts, shall hold their offices during good behaviour, and shall, at stated times, receive for their services, a compensation, which shall not be diminished during their continuance in office.
“During good behaviour” means unless they have been impeached and subsequently convicted, they are to hold onto their office. What Jefferson did was blatantly unconstitutional, and the Supreme Court rightly corrected him on it.
