The nullification movement is something that has been pushed by the Tenth Amendment Center and other people concerned with limiting Federal power. Basically, the goal is to help states reclaim their sovereignty. Instead of letting the federal government hand down dictates at will, our founders provided us with the means to push back.

I am in favor of every means of exacting back power and sovereignty from government overreach that does no harm to individuals in the process. I do not advocate defiance of every law, but I do see it fit to have the states stand against unjust laws as well as the individual, in the most prudent way possible.
