Common Core standards are an initiative, started by a coalition of state leaders of both parties, to establish a gold standard set of educational standards in math and English education.
Rather than look at the facts about where the Common Core standards came from or what they contain, conservative activists are spreading the usual paranoid fantasies about how the standards are a conspiracy to impose liberal beliefs on school children. Perhaps the idea that kids would grow up being able to read facts for themselves and perform basic mathematics is too much for the anti-science brigade.
