Out of control federal judges are just one of issues that Congress abrogated long ago. They have the power of impeachment over federal judges and are thus partly responsible for the problem for declining to wield that authority.
To be fair, the reluctance to remove judges has been the norm for most of the nation’s history. Add to that the difficulty of doing so at the federal level. The requirements to do so are the same as those for removal of a president (i.e. majority vote of the House and a 2/3 majority of the Senate). Nevertheless, we no longer live in normal times, and in particular when presidential impeachment has been trivialized by the democrats, judicial impeachment should no longer be off the table.
I would welcome an impeachment strategy if I thought it would work, but I don’t see how it can. Maybe it could inspire political action like voting dems out of the White House, but neither federal legislative body seems willing to help.
