The very belief that people are "sheeple" is part of the problem. That's part of the attitude that is the issue here. The thought process that somehow anyone that supports Paul is enlightened and anyone else is mind numbed masses that are brainwashed and dumb.
Paul has a great message, its how you put across that message that's going to matter. Part of it is understanding that the vast majority of the country are not die hard, non stop, political junkies. They don't know the ins and outs of how everything works, nor do they want to. They're not stupid, its just not their thing. Its like trying to talking detailed football play plans to someone that just barely watches it during playoff's, or going into details about the specs of your massive fast new alienware computer to someone that mostly just uses it for Word and email. Its not that they are stupid, its just not what they use it for.
Figure out how to get across Paul's message in a positive way, that is simple to understand and is not presented in a manner that you're basically telling people "Believe this, or you're stupid, unconstitutional, and brainwashed". Show that you understand that while you may not agree with the other candidates, that its not some kind of cardinal sin that they do, but then show them why you think Ron Paul is BETTER, not why their guy is "worse" or why Ron Paul is the "only" one and everyone else is a fraud.
I think that's the biggest issue with the grass roots movement of Paul now. It has became a very elitist thing, exclusive. I think in part that's what drives it to being quite easily the most prolific grass roots movement of the past 2 decades at least...but its also why it has trouble expanding out farther then it is at the moment. Few people in the general population are swayed by being told their stupid and wrong, or being treated like their "sheeple".
