A school superintendent should know better than to get in to the middle of a political firestorm.
Unless the school board is really behind him on this he may be looking for a job when his contract is up.
Then again if the school board backs him and the community is more sensible the school board members may have more evenings free for pinochle or bowling in the future.
Not to mention the fact that the companies mentioned seem to have no fear with respect to employing illegals; I truly believe that people who employ these workers should face jail time. If enforced vigorously, a great part of the incentive would be removed.
