My younger sister has suddenly turned into a Ron Paul fanatic with bumper stickers all over her car. The fact that she is also involved with Code Pink in some way should tell you something about Ron Paul, or at least tell you something about some (though not all)of his followers.
I know what it tells me. He's an popular candidate that can draw from all facets of society instead of a shrinking handful whose only concern, even above limited government, is to continue Wilsonian adventurism. Republicans can continue with the folly of police action if they want. However it's a cause that should never have began and frankly won't win them any elections if they continue pushing it.
Defend the nation yes, and Rep. Paul is all for that. However don't continue 'nation building'.
