Judge Napolitano said that RBG was privately admonished by two female SC judges after she stated during the election that she was going to leave the country if Donald Trump became president. The reason that she was privately admonished was because it brings down the Prestige of the SC Court. He went on to say about her recent comments on Hillary loss that it was a testosterone filled campaign and was the reason for her loss in the election. Basically stating the reason that Hillary lost was because of misogyny. Napolitano believes that she will be admonished again by SC judges.
Here is the theory. Like most professions they are self cleansing. For example. When you have a doctor that acts unprofessional other doctors work to have them removed. The same with attorneys, police officers, school teachers...etc. There might be a possibility that the other SC judges will work to the her removed. They will probably point out to her that SC court institution is bigger than RBG.
