Ohio Governor John Kasich went on the attack on Sunday against top Republicans who have rejected Common Core, claiming they have switched positions purely for political gain, even when they know the attacks made on the standards are false.

Common Core has been a popular punching bag for many Republicans seen as 2016 presidential contenders. Rand Paul, Bobby Jindal, Scott Walker and Mike Huckabee have all taken their turn bashing it.

The most common line of attack claims that Common Core, which began as a shared initiative between many state governments, has become a means of federal control forced upon states by the Obama administration. Jindal has been a particularly strong proponent of this argument, filing a federal lawsuit against the government claiming that Department of Education incentives such as Race to the Top amounted to an illegal effort to nationalize curriculum.

Kasich, however, said on Fox News Sunday that such attacks are bogus, and accused his fellow governors of not merely being wrong, but also of being dishonest.
