Real judicial officers have rules which govern their behavior, a code of judicial conduct, which are intended to protect the integrity and impartiality of the courts. Most prohibit judges from publicly taking positions on issues, which is why I can come here, a private board, and discuss politics, but I can't campaign for a candidate or issue.
If she is a real judge handling issues like custody cases, I would consider filing a petition to disqualify with the state supreme court, and seek to have her removed. I would also consider filing a complaint for conduct unbecoming if she wore that in court while presiding over hearings. It makes the court look bad.
