It is pretty much impossible to discuss the relative quality of the Common Core standards, because there is no good framework for doing so, and they are so messily constructed. Basically everyone seems to assume that all standards are awful, so whatever, and better one awful thing than 50.
In the end though, the Common Core will slowly sink into irrelevance because it is just so shoddily put together. I've spent enough time on that topic over the years, I'm not going to try to re-prove it to you now. But as support slips, it is unlikely the official debate will allow the possibility that they simply were poorly designed and written at every level of detail. On the ground, this reality has to be creeping up on people. Reporters and columnists aren't going to see it.
