The DNC communications team appears to be very sensitive about the Common Core State Standards and the issue of local and federal control over schools.
In a May 3 email expressing frustrations about the content of a video emphasizing that the "GOP doesn't appreciate teachers," Eric Walker, a deputy communications director at the DNC, wrote the following:
"A) Common core is a political third rail that we should not be touching at all. Get rid of it. B) Most people want local control of education so having [then-GOP presidential candidate Ted] Cruz and [now-GOP nominee Donald] Trump saying it on a DNC video is counterproductive. Would get rid of any references to that."
Presumptive Democratic nominee Hillary Clinton supports the common core, as do two of her big backers, the National Education Association and the American Federation of Teachers. It's taken a political beating on the national stage from both Democrats and Republicans, although most states that originally adopted the standards have stuck by them.
