I doubt you'll need to worry about it. There's very little about Ron Paul's policies with which I disagree (I do think he's softer than I might personally prefer on some facets of national security, but I don't think he's nearly as bad as many of his detractors claim); but that doesn't really matter, because I think he's too old for another Presidential run. He and Carol really deserve some time to take it easy, stay off the national stage and just tend to their district. (IMHO).
Mind you, I think (and hope) that he'll still be a great (Constitutionalist, if admittedly quirky) Congressman for years and years to come. But President? No, I think he's just too old to run an effective campaign anymore.
Assuming Rand Paul wins in Kentucky, I expect he'll become the new torchbearer for the Paul faction. And, since Rand seems to be at least a couple of degrees stronger on national security than his dad Ron, I expect that many 'round here will have an easier job supporting him in the US Senate. (But Rand Paul for President? I can hope, but it's probably not likely in the near term. 2012 is shaping up to be Palin's turn, at least if she can prove herself in the Primary vetting process the way every candidate has to do).
