Moreover, like it or not, all impeachments are political. Pretending they're not only leads to self-delusions.
Another self delusion is that the judiciary is this magically apolitical, sacrosanct branch of government. What a bunch of crap. There is no apolitical action in government.
You need to work on your imagination since the reality is that the Founders believed impeachment would be rare particularly with judges. They were given lifetime appointments during good behavior. Making unpopular decisions was not considered "bad" behavior subject to impeachment. Making the judiciary independent was tremendously important to them and the writings on the subject make that point clear. The last thing they wanted was a judiciary dependent upon the good will of the electorate.
Initially the trial by the Senate of impeachments meant that the people had little or nothing to say in this matter since Senators were appointed not elected. Popular opinion or beliefs were excluded from having any influence in an Impeachment trial.
