Stephanie Simon writes in Politico.com that Arne Duncan is not really in favor of Common Core. Common what? Common who? Never heard of it. Ah, how soon politicians forget what they said last week, last month, last year. And they expect us to forget too.

She writes:

“COMMON CORE LOSES ITS BIGGEST CHEERLEADER: It was less than a year ago that Education Secretary Arne Duncan delivered a no-holds-barred defense of the Common Core in a speech to newspaper editors. He cited example after example of the benefits of common standards: Teachers in different states could use the same lesson plans; children of military personnel could move across country “without a hitch” in their schooling; and, first and foremost, “a child in Mississippi will face the same expectations as a child in Massachusetts.” In short: “I believe the Common Core State Standards may prove to be the single greatest thing to happen to public education in America since Brown v. Board of Education,” Duncan said.
— That was then. This was Tuesday: “Just to be very clear with this group,” Duncan told the House Appropriations Committee, “I’m just a big proponent of high standards. Whether they’re common or not is sort of secondary.”
— Duncan immediately added that his stance was “not news.” And his spokeswoman, Dorie Nolt, later pulled up audio from a press breakfast in January where Duncan was asked about whether the term “Common Core” was politically radioactive. “We’re not interested in the term,” he responded then. “We’re interested in high standards. There are a couple ways to come at it.” Indeed, the administration has never required states to adopt the Common Core; it just offered financial and policy incentives to adopt higher standards – and embracing the Common Core happened to be by far the quickest and easiest way to hit that bar.”

So what gives?

Here are some possibilities:

1. The Common Core standards have become so controversial that Duncan wants to pretend he had nothing to do with them.

2. Duncan has been warned by his advisors that his support and Obama’s is actually dragging down the poll numbers for the Common Core so the best way to help them is to back off.

3. Someone is planning to sue the U.S. Department of Education for illegally interfering in curriculum and instruction by supporting the Common Core, so Duncan must pretend he had nothing to do with their swift adoption by 45 states. His lure of $4.3 billion was just a coincidence.

4. Duncan realized that his cheerleading contradicted his insistence that the Common Core was “state-led.”

Can you think of another reason that Duncan forgot that only a year ago he said the Common Core was the most important development since the Brown decision?
