A recent Rasmussen Reports survey finds that Americans with school-age children are increasingly questioning whether Common Core national standards will really improve student achievement—and they’re not happy with the answers. According to Rasmussen:

…just 34% of American Adults with children of elementary or secondary school age now favor requiring all schools nationwide to meet the same Common Core education standards. That’s an 18-point drop from 52% in early November of last year. Forty-seven percent (47%) oppose the imposition of the national standards, compared to 32% in the previous survey.

The percentage of undecided respondents remains unchanged at 19%.

What’s so striking about these findings is that over the past several months a slew of other polls have purported showing overwhelming support for Common Core, and Republican candidates who oppose it likely risk eroding their support base. The Heartland Institute’s Robert Holland explains why those results are so “fishy,” but he makes another important point to keep in mind: The more people really learn about Common Core, the less they like it:

Here and there, some polls are beginning to reflect the growing anger of citizens over undemocratically imposed nationalized standards they like less the more they find out about them. A little-noted University of Connecticut poll conducted the last week of April found just that: Opposition was highest among people who said they were most highly informed about CC. …

Citizens should closely scrutinize all public-opinion surveys for embedded bias. A critical assessment of the accumulating data indicates a growing proportion of parents who have brought themselves up to speed independently on Common Core—as opposed to being pollster-led—oppose this top-down imposition of shoddy, one-size-fits-all standards and subjective testing on their children.

Political candidates trying to ride the Common Core coattails to a victory on election day had better hope their constituents aren't well-informed parents.
