Seth is definitely a Dem supporter, though despite his squishy politics he makes a mean champagne risotto. What is funny: both Congressman Paul and Seth McFarland have ties to Duke, but I believe that is where their convergence ends.
Mike Judge is definitely a "closeted" supporter of Ron. In '96-'97 the start-up music on 203 Canon House office computers was that of "King of the Hill". Most of the staffers, especially Norm, were convinced the fictitious town in the series, Arlen, Texas, was in Ron's district. Norm even had/has a dance... and if you've ever had the pleasure of watching Norm dance to the KOTH theme music while wearing his "The King (Elvis) meets the President (Nixon)" threadbare t-shirt, you've had the pleasure of knowing first rate sudden comedy.
Reason Magazine has published articles fleshing out the connection: much of the "situational comedy" in "King of the Hill" is based on the theories of F.A. Hayek, especially those involving the State agencies and their meddling in the lives of Hank and his family.
Clint Eastwood's cardboard cut-out from "Fist Full of Dollars" formerly adorned the refrigerator in 203 Canon.
The list is long, actually...but most of the celebrities listed on the AforSG and LP web site are more libertarian than constitutionalist.
The thing is, based on observation, it is pretty evident Congressman Paul is not big on celebrity endorsement despite receiving hundreds of personal letters of thanks from top-tier celebrities from all over the world. There is a fine line between endorsement and the cult of personality, a line that Congressman Paul never crosses. Of course, he appreciates the support, but at the same time (and this is strictly my opinion,) people often confuse the Congressman for something he is not: a politician, as opposed to a citizen-statesman (there is a difference). Congressman Paul does what he does, so others can do what they do, with a view to eventually never having to do anything by letting the Constitution do the "talking."
I also think some of the views expressed in the forum are ever so slightly short-sighted. In other words, I am of the opinion that we're observing the greatest schism in American Politics since the Civil War in so far as this is the beginning of the redefinition of both major parties. On one side, you have Ron; on the other, the rest of the political landscape (though a few candidates intermittently visit Ron's side of the line.) The American Political Tradition is evolving, and in a couple of years time, the left-right association will be a thing of the past... an indirect objective of Congressman Paul's for the better part of his political tenure.
As the movement gains momentum, and it will, this difference will become evident and as it does I believe more will be done in the mainstream pop circles to both worship and vilify this changing perspective. After all, most celebrity is built on the act of creation; the only candidate in this race, and really the only representative in American Politics that advocates unfettered creative fidelity free of subsidy and entangling alliances, and thus truly creative, is Ron Paul.
Before closing, I saw Greenspan listed. As many well know, Greenspan was a devotee of Ayn Rand for the early part of his career. Though he stepped into a Statist mess in running the Fed, much of his commentary before and after his tenure there is staunchly libertarian, including but not limited to his most recent commentary regarding "private currency" as the next big thing. You'll also find that Greenspan engaged Congressman Paul with a respect and reverence that he did not pay to others knowing full well though they may have disagreed on certain nuances of policy, Greenspan knew/knows that Congressman Paul did more than his homework to the point of completely understanding the entire apparatus, only to make a logical decision to oppose it. Greenspan was bought and paid for, almost begrudgingly so, and I think Greenspan maintained enough personal integrity to recognize a man of honor and principle free of compromise.
