Personally I think it’s pretty difficult to be a constitutionalist and hold office. His overall votes suggest he is as close as you can get. I’ve been following him for years and while I haven’t agreed with everything he has said, I do think he is a much better choice then any of the candidates in the running right now.
Maybe take a look at the ron paul library which will help you search for the subjects of importance to you, discover things for yourself rather then rely on some of the hysterical comments of the anti-paul rabid wolves here.
