I haven't seen the whole interview, but from the fuller quote that was posted, Paul is talking about how when tyranny comes, people are often deceived by wolves in sheep's clothing.
The bible talks about this, and btw, the bible also talks about how the devil himself can masquerade as an angel of light. (click) If discussing that idea is insane, I guess the bible is also insane.
As far as this interview goes, the one thing I will criticize Paul on is - he evidently should have dumbed down what he was saying, or spelled it out like he was speaking to a 10 year old - for the people who are all too eager to (willfully) misunderstand him, in order to use it as ammunition against him.
Our country is over 200 years old, and no such thing has even come close to taking place, even after 8 years of the Clintons.
