Insofar as courts have usurped the powers of Congress and the States, it is not what the Framers designed. They did not corrupt the Constitution.
They gave us the power of impeachment, the exceptions and regulations clause, and just as important, every inferior federal court exists at the pleasure of Congress. IIRC, Rep Pete King said Congress could reduce the entire federal court system to John Roberts sitting at a card table with a candle.
In short, there should be at least a couple judicial scalps from impeachment hanging on Congressional belts every year. Impeachment and conviction just means a firing. What is the big deal? Is there a lawyer shortage? Impeach a couple judges per year and the rest will get the message.
The problem is Congress kinda likes the courts and administrative agencies making the tough decisions. It is a fundamental law of thermodynamics that when the heat is on courts or regulatory agencies, it is not on Congress. We the Sheeple at large are too ignorant to figure this out.
You’ve got it exactly.
The Constitution purposely leaves grounds for impeachment of judges vague and does not preclude solely political reasons.
And the House of Representatives should employ the power of the purse - the only power they have. Until they do, castrati like Boehner are logical choices.
