With the Iowa Caucus quickly approaching, Marco Rubio is going on the offensive, and he appears to be making his opposition to Common Core a central focus of his pitch to conservatives.

While campaigning in Iowa last week, Rubio emphasized that eliminating federal support for Common Core would be among his top priorities if elected president. As reported by Education Week:

In a speech last Tuesday in Waterloo, Iowa, Sen. Marco Rubio, R-Fla., excoriated the federal government under President Barack Obama for, among other things, “trying to take over our schools with common core.”

“I will repeal every single one of his illegal, unconstitutional executive orders that he has put in place, and I’ll do it on my first day in office … that means we are stopping any and all work on imposing common core on this country,” Rubio told the crowd.

Following up on that message this week, Rubio’s Conservative Solutions PAC launched an ad attacking Chris Christie’s record on, among other things, Common Core. You can watch the full spot below:
