Rick Santorum, who dropped out of the GOP presidential primary, touched on that theme in his Aug. 28 speech at the Republican National Convention in Tampa:
"A solid education should be the second rung on the ladder to success, but the system is failing. President Obama's solution has been to deny parents choice, attack private schools and nationalize curriculum and student loans. Mitt Romney believes that parents and the local community must be put in charge -- not the Department of Education."
Has Obama tried to "nationalize curriculum"? We could not track down Santorum to ask him to explain his statement, but Education Week wrote that his statement was "an apparent dig at the Common Core State Standards, which are not an initiative of the federal government, but have been embraced by the federal Department of Education." PolitiFact rates Santorum's claim Mostly False.
