Why Are Some Florida Former GOP Leaders Supporting Common Core? Are They Really Republicans?

From Truth in American Education and Countering Florida GOP Leaders Defense of the Common Core:

Five former Florida Republican Party leaders have urged the state GOP to ignore the parents and teachers who object to the centralization of education through the Common Core State (sic) Standards. Like other Common Core proponents, they repeat the talking points; like the others, they fail to produce evidence to support their statements. Below is a point-by-point response to their claims.

Why are unelected officials offering their misguided opinion on Common Core especially when the Republican National Committee has come out against the standards?  From the RNC resolution against Common Core State Standards:

RESOLVED, the Republican National Committee recognizes the CCSS for what it is — an inappropriate overreach to standardize and control the education of our children so they will conform to a preconceived “normal,” and, be it further

RESOLVED, That the Republican National Committee rejects the collection of personal student data for any non-educational purpose without the prior written consent of an adult student or a child student’s parent and that it rejects the sharing of such personal data, without the prior written consent of an adult student or a child student’s parent, with any person or entity other than schools or education agencies within the state, and be it finally

RESOLVED, the 2012 Republican Party Platform specifically states the need to repeal the numerous federal regulations which interfere with State and local control of public schools, (p36) (3.); and therefore, the Republican National Committee rejects this CCSS plan which creates and fits the country with a nationwide straitjacket on academic freedom and achievement.

Do the five unelected Republican officials in Florida need to change parties?  By supporting the Common Core standards, are they supporting the current administration's blueprint for education?  Why would these self proclaimed Republicans oppose the Republican National Committee's call to repeal Common Core?
