A case is currently pending in the U.S. Supreme Court on the Delaware law that says all state court judges (on most of the state courts) must be members of a party that has voter registration of at least 5%. Therefore, an independent can never become a state court judge. The Third Circuit had invalidated the policy, and Delaware is trying to persuade the U.S. Supreme Court to hear its appeal. Carney v Adams, 19-309.
On October 2, seventeen law professors filed this amicus in favor of the Delaware law. Their names are in the Appendix. The state will file its own brief later on October 7.
Delaware does not elect any judges; they are all appointed.
