May I suggest a watching of "The Manchurian Candidate"? (the 2004 version, directed by Jonathon Demme). There's also the original 1962 version with Frank Sinatra but I think Demme's version speaks more directly to us since it's more high-tech.

One takeaway from it - Demme never specifies political parties in his film. If you look, you can see that he uses red AND blue for the political things, implying the idea of a Uniparty.
