Week 6 Discussion 11 unread reply.11 reply. A great many factors shape Americans’ political ideology. Some of the most common have to do with where we live and how we identify ourselves and with our communities. Which of these factors of identification has a greater effect on polarization, race, class, or geography? (This is not to say that the others do not affect polarization, but which would you argue has the greatest impact on the polarization of Americans?)These factors are of course not mutually exclusive--what about when these factors intersect? Be sure to use specific evidence to support your argument.
