Yup. Which is the same thing the RNC did to Ron Paul in 2012. I watched all 3 happen. They deliberately box out the people they don't like, and their methods are getting more and more obvious, especially as more people pay attention to this deliberate boxing out, because it signals that our democracy is quite weak right now, and not really representing public opinion in any meaningful way anymore because of the level of corruption in both of the two main parties, and thus the government as a whole by extension.
