While it is true every judge on the ballot was elected (later), by my count Injustice Watch reports 27 of the 77 judges up for retention first became judges when they were appointed by the Illinois Supreme Court power to fill vacancies, not by elections. 12 of those in 2017, 1 in 2018. 1 is up for retention on the appellate court. A judge mentioned in this Chicago Tribune article on the questionable application of that power (Marsalek) is up for retention this year.
