The ruling class learned 2 very important things from this:
1. If you do not control the media, you can be shamed by public opinion into giving up your serfs. The cure for this: control the media. They have acted on this and now control almost all of mainstream media.
2. It is impossible to control large amounts of people if they know they are ruled and do not want to be ruled. The solution: Give them the illusion of choice and convince them that they are a free people. The ruling class can still maintain control by only offering puppet candidates to the masses.
So what does all this have to do with the RNC?
