Scientific explanation for Red States

The Voice of Bad Science, an article by Ben Rothke, says what I've believed all along -- that Americans are dumber than a sack of hair.

... Americans are woefully uneducated in the rudiments of basic science. This ignorance makes these types of consumers prey for supplement companies. The fact that tens of millions of American’s believe in government conspiracies, Bigfoot and Roswell are dubious signs. Lawrence Krauss writes in “Stop the Flying Saucer, I Want to Get Off” that “mountains of statistics suggest that the public is far more susceptible to scientific nonsense than political nonsense. More than half of Americans are unaware that the earth orbits the sun and takes a year to do it”.

Although the article is ostensibly about radio advertising, I can't help but draw parallels to why there are so many John McCain supporters or why there are so many dittoheads.
