I agree that there really is no way for the layman to know. The states all vary as well. Meaning something like 10 states have partisan votes (party listed next to name in ballot). About 20 have non partisan, so they don’t list the party. Many have Yes/No retaining votes without listing a replacement, just decision to keep. Then some states have policies where the judge must be confirmed by the state Senate, and others approved by their state Congress. Beyond that, I don’t remember much, it is way to much for a person to keep up with and their should be independent bodies that evaluate performance/ judgements. I don’t know a perfect way to set it up though, as corruption is everywhere.
