Hamilton, Madison & Thomas Jefferson show us that Nullification is the Answer.3. Hamilton shows in Federalist No. 28 (7th para) that if the federal government invades the rights of the People, they can use the State government as the instrument of redress:
…in a confederacy the people … may be said to be … the masters of their own fate. Power being almost always the rival of power, the general [federal] government will … stand ready to check the usurpations of the state governments, and these will have the same disposition towards the general government. The people, by throwing themselves into either scale, will infallibly make it preponderate. If their rights are invaded by either, they can make use of the other as the instrument of redress…. [emphasis added]So! When the People of the State of Missouri approved Proposition C nullifying obamacare, they properly made use of their State government as “the instrument of redress” against the usurpations of Congress & the Executive Branch.
And since State officials and many Citizens have taken the Oath to support the U.S. Constitution (Art. VI, clause 2), it is their SWORN DUTY to nullify – to refuse to obey – unconstitutional and pretended federal “laws”, such as obamacare.
