Which Came First: the Chicken or the Egg?

          While I may be thinking about American polarization way more than the average Joe, due to my seemingly endless junior theme research, I have come across many interesting thoughts stemming from the theme of polarization. My theme specifically focuses on political polarization in our country, the gap between the democrats and the republicans, but when researching political polarization it is nearly impossible to run into other types of polarization as well. 

          The book "Red State Blue State Rich State Poor State" by Andrew Gelman looks at the geographic divisions caused by political divisions. Where people who live in certain states are classified as "red" or "blue". While these divisions may seem second nature to anyone who has watched the states light up on the election night news, there is more then initially meets the eye. Gelman argues that richer states, such as New York, Massachusetts, and Connecticut are blue states, or vote democratically. Where as poorer states, such as Mississippi, New Mexico and Arkansas, were red states, or republican states. Even within these state lines, are districts that are either red or blue. This shows proof of geographic polarization especially people living in areas with people who agree with them politically. 

          So what came first, I ask myself, Political Polarization or Geographic Polarization? In other words, do people live where they do, be it states or districts, because people in the area agree with their political views? Or are people polarized politically because where they live. The book "Red Families v. Blue Families" discusses how family values and views on social issues divides us politically, and therefore geographically. So with our morals, political views and geographic location all playing a part in who we are, I ask: which causes which? I would be interested in hearing anyones anwser to this question, but while I continue to research I begin to think that maybe there isn't an anwser.
