I’ve been involved in School Board elections (usually as an opposition campaigner) in every community where I have ever lived for the past 50 years. Have you ever tried to bump someone off a school board? It is nearly impossible.
In the first place, the positions are never representational (in my experience). It’s always the top 3 vote getters, or top 2. IOW, they don’t represent neighborhoods, or voting districts. Name recognition means everything. So the same old people get elelcted. Even if someone does not want to continue to serve, they seldom say that. The get themselves re-elelcted and then they resign so that their successor is appointed by their friends on the board.
I have known of only one school board member to ever have been re-called and that involved misappropriation of funds involving the hiring of an unpopular Superintendent. And then she went on to be re-hired by her friends on the school board and was given a very cushy position as an administrator.
School board elections have more impact on property owner taxes than most any other election that gets held, and most of us don’t know the names of our school board members and what they stand for.
