True. But President Trump's argument is that School Boards represent the entire school district, the Principal represents that school. An elected Principal would be better served to help the parents than the teachers.

Let's say we have a small city of 70,000 people with three high schools, three middle schools and 12 elementary schools. Each district would be represented by one Principal and would likely the parents at school district meetings. In theory, they would be answerable to parents before teachers.
