Ron Paul supporters really need to make sure they know all about Michael Scheuer and his opinions. It is not a dove-ish foreign policy. There is a clear distinction between non-intervention everywhere possible, and pacifism.
Ron Paul's biggest failure, if I dare call it that, is not clearly defining that when given the opportunity during debates. In Ron's defense, there's so much nuance in these arguments that you just can't convey an entire response in a minute or two.
