What this office does

Trial court judge. A trial judge presides over criminal and civil cases at the first level: bail and pleas, motions, trials, sentencing and civil judgments. Judges are bound by state law and appellate precedent and are barred by judicial conduct rules from campaigning on how they would rule. Most states elect trial judges on a nonpartisan ballot; the term and the courts a judge may sit on vary by state.

This race. Elected by district: only voters who live in the district see this race on their ballot. The sitting officeholder, Erin C. Hannigan, is on the ballot. One name is on the ballot for this seat.

This list comes from official election records but may be incomplete. It can miss, for example, late or petition candidates and some city, school and district races. Your official sample ballot is the final word.
