Correct. Impeachment is one way. But this would probably best be done through reorganization of the federal courts, and in doing so, eliminating positions. Congress established them and can reorg or abolish them as it see fit. Once the scum are laid off you can establish new open positions and nominate new judges that are not hacks.
“Congress established them and can reorg or abolish them as it see fit. “
The problem with that is that the GOPe will not lift a finger to impeach any of them since they get paid by people who need a complicit judiciary to “shape the country” to their personal wants and needs. Maybe we had better hasten the Convention of the States before many more of them go Blue.
