The question naturally begs a larger question: How can a country, with the world’s highest national GDP, and absurdly complex systems regulating everything from credit default swaps to nuclear missile safety, possibly allow onto its national stage men and women of such transparently inferior intellect?
The easy answer is that there has always been a long, pathetic history of anti-intellectual paranoia in American politics, as Richard Hofstadter documented in his book Anti-Intellectualism in American Life (1963). It is like kudzu. You just can’t kill it. No matter how advanced the U.S. becomes in technology, biomedicine, and weaponry, it not only attracts, but promotes, under the rubric of equal opportunity, a confederacy of dunces as Presidential candidates.
