For the democratic process to run properly it necessitates the voter to have some knowledge of what he is voting on. If you are going to vote on something like stem cell research you should at least know what it is, correct?  Well the question is, how can Americans vote on such things as global warming, stem cell research, cloning and what have you when basic scientific fundamental concepts fly right over our heads.

“American adults in general do not understand what molecules are (other than that they are really small). Fewer than a third can identify DNA as a key to heredity. Only about 10 percent know what radiation is. One adult American in five thinks the Sun revolves around the Earth, an idea science had abandoned by the 17th century.”

wow, 20% of the country.
