Something Common Core opponents need to recognize is that people like the concept of uniform national standards (as does the Mad Biologist):
Opposing national standards per se is doomed to fail, especially in an era where families have to move repeatedly due to work. Many parents have experienced the frustration after their kids have switched school districts and are either ahead of or behind their new peers. The real problem with the Common Core is that this particular set of standards is mediocre. We have standards that work–we should adopt those in every state, instead of reinventing a square wheel.
