Gary Johnson v. Ron Paul As Communicators?

This post by economist Steve Horwitz about a blogger conference call with Gary Johnson is a few weeks old, but I thought I'd flag it anyway as of interest since it's not as though the information in it is time sensitive. I think I've said before on here that while I like Johnson a lot, I agree with Horwitz that he has a near zero chance of winning the Republican nomination, and so I'm reluctant to get too attached to his candidacy. The comparisons with Ron Paul are also especially interesting. Like my husband, I think that Johnson comes off as less kooky than Paul and that this lack of kookiness could be a real boon for libertarianism. Horwitz's claim that Paul is better at popularizing economic ideas is an interesting one, though, and suggests a real weakness for Johnson's campaign going forward. While I hope that isn't true, and is not something I've noticed personally, I can see how it could be a point of real liability. I would just be disappointed if that's indeed the case.
