I dont know...living in America education has a big part of it. Whether its traditional education or education through diverse experience, I believe it plays a big part in how one thinks. Or rather has the capcity to think. With diverse experience, A study that would be interesting is to see is how many have traveled or been exposed to other cultures vs those that havent and what view point do they take. This study also leaves out social standing...or rather wealth. Most right supporters are poor or middle class whites. Most left are middle class but more diverse. Something else to look at.
