But that doesn't imply to impeaching federal judges based on disagreement with their judicial philosophy. It will only end up hurting politically, and essentially giving the other side more votes in Congress.
Impeaching a judge who has ignored the text of the law to impose his own values upon the case is not "disagreeing" with his judicial philosophy. It's impeaching him for "Treason, Bribery, or other High crimes and Misdemeanors," of which willfully disobeying his oath of office and subverting the rule of law is a clear example. Here is the oath every federal judge swears:
“I, ___ ___, do solemnly swear (or affirm) that I will administer justice without respect to persons, and do equal right to the poor and to the rich, and that I will faithfully and impartially discharge and perform all the duties incumbent upon me as ___ under the Constitution and laws of the United States. So help me God.”
