In, then ousted, then back in again, and (one hopes) out again next year.

A similar story played out in 1999, when the board removed most references to evolution, the origin of the universe or the age of the earth. Voters unseated conservatives in 2000, and a new board, dominated by moderates, changed the standards back.

Moderates hope the same thing will happen next year, when they vow to unseat conservatives in next November’s elections. Voters will fill five board seats next year, four of them belonging to conservative incumbents. A handful of candidates have already announced their intention to run.
