I've only seen the anecdotal common core stuff online, and the thought of that crap being taught in schools is truly terrifying.
I also think it was developed long enough ago that current administrations weren't involved and think it's largely been bastardized since. I think quite a few states have dropped it or have at least withdrawn support for it. A us news poll showed teachers dont even support it. So to say the state's created common core as it exists today is quite disingenuous.
