Gov. Butch Otter and State Superintendent Tom Luna say they made a mistake when they voted to buy a storage business with revenue benefitting Idaho’s public schools. Both politicians voted last August in a unanimous decision to buy Affordable Self-Storage in Boise as members of the Idaho Land Board. Storage industry officials accused the state of competing with the private sector, something both Otter and Luna are committed to avoiding. Other board members, including Attorney General Lawrence Wasden, Secretary of State Ben Ysursa and Controller Donna Jones, say they believe the purchase still makes business sense and fulfills their constitutional responsibility to maximize endowment earnings.
