Blue eyes run the White House?

I've started reading the Freakonomics blog, by the same guys who wrote the popular book.

If you haven't read the book, I highly recommend it. The authors make correlations and causations between things and events that people normally wouldn't think of. For example, lower crime rates and the legalization of abortion.

Anyway, in one of the latest blog entries, it is proposed that Fred Thompson will win the next presidential election because he has blue eyes. Apparently, every President since Richard Nixon has had blue eyes.

While men may not notice the color of another guy's eyes, women do. It was pointed out by female blogger, Noele Kensut.

The key to Kensut's argument:
"Today only 1 in every 6 Americans, or 16.7% of the population, has blue eyes. This percentage has been dropping in part due to immigration from non-European countries. A 2002 Loyola University study found that as many as 50% of Americans born in 1900 had blue eyes. The choice of an American with blue eyes for President may signal a voter preference for someone with deeper roots in America, vs. a relative newcomer."

It is also pointed out that John Edwards has blue eyes. But, since Edwards gets $400 haircuts and is generally more girly, he won't win. Then again, by that logic (being more girly), Hillary should win (although I'm sure there's an argument that even though she is female, she isn't more girly). Clearly, I haven't thought this through...

Another reason why Edwards won't win:
