As Jefferson and Madison told us with their Kentucky and Virginia Resolves, the States should interpose between the central government and the citizens of the States to protect them from unconstitutional laws through the process of nullification.
Read Tom Wood's Nullification which he believes is the best way to restore our limited constitutional Republic, better than getting people elected to office.
If enough of the population came to understand the intent of the Founders in granting only certain explicit and limited powers to the central government in Article 1 Section 8 and the retention of all other powers to the States or the people through the Tenth Amendment then the course of our country could be changed in the direction of greater individual liberty.
This is beginning to happen through the efforts of all the pro free market organizations. Watch the growth of www.studentsforliberty.org and www.YALiberty.org which are growing exponentially across the country in the colleges and high schools and worldwide. A greater percentage of future generations will be properly made aware of the virtues of the free market, of limited government, of individual liberty and adherence to the Constitution as time goes on. The day will come sooner than one can imagine given the nature of exponential growth.
Pass the torch and support these organizations. Make everyone aware of their existence and donate to them even a token amount.
