Reddit mentions of Mass Media and American Politics

these topics are interesting, and there are a lot of related subjects which would be beneficial to learn. I hope it's correct to assume you're in America.

i haven't actually read these linked books, just doing a little search for you because I miss my days studying politics

I think using the political scandals books would be really important. Because let's face it, yes politicians do lie but they don't always get off the hook. I think the book on rhetoric would also be super interesting. Learning about soviet / chinese society is interesting because they have it worse than us in terms of lying politicians (I'm a good patriot)

You should try and use historical-overview type texts for the bulk of citation. If you are quoting opinionated pieces, you can't just present their opinion as fact. You should reference the topic using the neutral sources as well.

By the way, an incredibly useful tool for constructing this kind of reading list is looking at the bibliographies of other books.
