Brainless?

I find it rather disturbing how the Republican presidential candidates de-emphasize education.
It shouldn’t take a brain surgeon to understand that a well funded, public educational system, with emphasis on math, science, logic and thinking, and free from religious indoctrination, is important for the future of the country.
Among the Republican hopeless, though, not even a brain surgeon seems to understand that.
Or, is Dr. Ben Carson simply concerned about the future of GOP if people learn too much real stuff?
One has to wonder …
