Why? It's not that bad to have an inmate in the board, since he won't be available to do any harm. Besides, the reason for a board (instead of a single administrator) is that other members are part of the decision process, too, unless they're all in jail. The recall process is available to the voters, too, just in case.
It's also possible that some voters disliked the other candidates and voted for someone they didn't know.
If someone votes for someone they don't know they should proudly let everyone know, how smart they are.
It is no secrete that others have died to allow us the freedom to vote.
Elected officials have roll call votes, and they get their power from the people, the people should have roll call votes to set the example of accountability for those elected.
Secrete elections and black balling candidates are fine for social clubs and fraternities, but the bar should be higher for our form of self government.
