Numerous politicians—particularly Republicans—have executed breathtaking reversals in their positions on Common Core as the political head over the education standards intensified. To see how the conflict has played out, read Business Gets Schooled.
Chris Christie
Yes! “We’re doing Common Core in New Jersey, and we’re going to continue … I think that part of the Republican opposition … is a knee-jerk reaction … that if the President likes something, then the Republicans in Congress don’t.” —August 2013, at an education conference, Las Vegas
No! “We must reject federal control of our education and return it to parents and teachers. We need to take it out of the cubicles of Washington, D.C., where it was placed by the Obama administration, and return it to the neighborhoods of New Jersey.” —May 28, 2015, speech at Burlington County College, N.J.
Jeb Bush
Yes! “Because people have a different view of what Common Core is, am I supposed to back away from something that I know works?” —May 2015, Nashville
Er, I think so: “The term ‘Common Core’ is so darn poisonous, I don’t even know what it means. I’m for higher standards—state created, locally implemented—where the federal government has no role in the … content or curriculum.” —Aug. 14, 2015, Iowa
Carly Fiorina
Yes! “Internationally benchmarked standards and assessments help ensure our students graduate high school prepared with the skills necessary to succeed in the our 21st-century economy.” —November 2009, “Carly on Education,” position statement for senatorial campaign
No! “I think Common Core is a really bad idea. It is a giant bureaucratic program, and we have demonstrated over 40 years that the Department of Education can get bigger and bigger and bigger, and the quality of education continues to deteriorate.” —May 6, 2015, CNBC interview
Mike Huckabee
Yes! “Rebrand it, refocus it, but don’t retreat.” —November 2013 speech, Council of Chief State School Officers
No! “We must kill Common Core and restore common sense.” —2015, Huckabee campaign website
Steadily in favor: Hillary Clinton, John Kasich
No clear position: Bernie Sanders
Always opposed: Ben Carson, Ted Cruz, Rand Paul, Donald Trump
