PIERRE, S.D. – South Dakota may be one of the most politically conservative states in the nation, but Common Core opponents can’t find many friends in the state Legislature these days who share their concerns about the new, nationalized learning standards.

The Associated Press reports that “a slim majority” of lawmakers in the South Dakota House rejected a resolution on Wednesday that would have halted the expansion of Common Core. The state began implementing the one-size-fits-all math and English standards this school year.

That vote marked Common Core opponents’ second setback in the last week.

Last Thursday, the GOP-controlled Senate rejected a bill that would have funded a two-year study to determine – once-and-for-all – if Common Core math and English standards are really an upgrade over the ones they replaced, the AP reports.

State Rep. Jim Bolin, a leading Common Core critic, seemed undeterred by Wednesday’s vote.

“You don’t get into a mess overnight, and you don’t get out overnight,” Bolin told the news organization.

Despite the recent disappointments, Core opponents may succeed in passing a bill that would prevent the state from adopting other nationalized learning standards for science and social studies until 2016, and another that would firm up privacy protections for student data, the AP notes.

Those may be small consolation prizes for Core critics who probably expected more support in an overwhelmingly GOP-controlled Legislature and from Republican Gov. Dennis Daugaard – who, by one analyst’s calculations, is the seventh-most conservative governor in the nation.

That just goes to show that while Common Core opposition is comprised of both Tea Party activists and teacher union leaders, support for the K-12 experiment is equally bipartisan – ranging from conservative governors like Daugaard to President Barack Obama.
