I saw the article, and it does indeed show this, however, I'm not sold that education is the only criterion when it comes to how someone votes... or does anything else, for that matter
It's far too simple of a cause-and-effect type of deal for this to be the only factor, or even, for this to be a factor at all, perhaps. The world is a bit more complex than chucking everything up to how someone does something based solely on their administered level of institutional education
I've been just a tiny bit more skeptical of all of these cause-and-effect type stories ever since I read Nassim Taleb
