But how many people can name even a single person on their local school board? How many can account for what that person's platforms are regarding the school? How many can account for anything that person has done while on the board? Where would you even go to find out what your local school board is doing? How many of your school board members have observed the day-to-day goings on of your local schools?
The system seems fundamentally broken to me. It's no wonder school administrations are so incompitent - especially in larger districts.
Regardless of the process, a voter's vote is a vote and the sum of the votes (including voters who do not vote, "I don't care." is a valid vote) is the democratic will of the people one way or another.
Also, if you truly do want to argue that voters should vote a certain way then you should plainly say so instead of being disingenuous.
