The superintendent is hired, not elected. And, once he gets hired, it takes dynamite to get him out. The superintendent is the dangerous one. School board members are usually well-meaning but ignorant of how things work. That's why they usually vote with and back any decisions by the superintendent. The superintendent is really the one who runs the district.
Tell me on how that is supposed to work!s\
