Johnson's movement is not 'within' Ron's circle, some of his staff, as with some of Johnson's, are both associated with libertarianism. However, it is important to realize that Ron, himself, was a paleoconservative before the libertarian party was ever created. He never made some of the concessions those who grew out of the party sometimes did. Some from the libertarian side I think may have been worried that Gary Johnson would draw some of Ron's support. But on this issue, Ron believes in US sovereignty and he is absolutely consistent on that, as with everything. GJ seems to have a 'cost benefit approach' which is, to me, mushy on principle and too willing to cede principle for 'pragmatism'. GJ came out for NAFTA, for example, while Ron, seeing it as a violation of US sovereignty to put foreign councils preeminent over local law, opposed and opposes it. There is no question that Ron is more of a free trader, but he also understands how much special interest cronyism and delivery of US autonomy is hidden in the 20,000 pages of regulation that stand between what NAFTA is and what free trade is. Ron is kinda a policy wonk, and doesn't go by the title of the bill.
Ron VOTED for the fence, though, because he thought enforcement and other issues were more important than the fence, but we fought a war for the Rio Grande. do we really not want our Ranchers and transporters to be able to use the waterway? That just doesn't feel like the Land of the Free.
Any how, please look deeply, because Ron shines the more you look. He DOES have issues with Club for Growth because he is considered a 'purist' on 'free' trade, putting US sovereignty, and freedom from barriers to entry to small enterprises above compromise, on some specific trade deals. You have to decide what is important to you, of course.
