Political institutions governmental and non-governmental. Compare political institutions, governmental and non-governmental actors, and political cultures in the United States and other states, distinguishing basic differences and similarities among them. That brings to me another point. It is totally fine to use mostly news articles. I know in college you are used to citing mostly books, but no credible books have been written on the primary that is still happening right now. So news articles are fine. You don’t have to be very scientific about it. Just make sure that they are credible news articles and not just something some random blogger posted on the internet. The NYT, Washington Post, US News and World Report are great sources for this. You should also try searching the Brookings Institute for a more in depth analysis. I also showed you articles from MSNBC and fivethirtyeight. Those are fine as well.
