I don't believe that I support Ron Paul for president, for one reason only. He's too isolationist, and is dangerous for that reason. But 200 years from now, when historians write of the collapse of the USA, I believe that Ron Paul will be mentioned.
As in: "If only they had listened to Ron Paul. He warned against the wild, excessive spending and the foreign adventurism that helped break the USA."
I doubt very much if Gingrich, etc. will be so mentioned.
