The Constitution clearly identifies very specific roles for the federal government. The Tenth Amendment clearly prohibits the federal government from inserting itself into any other role such as health care or intra-state commerce.
History shows that it is foolish to expect any of the three branches of the federal government to take necessary steps to limit the power of the federal government. That was again made clear when the Supreme Court failed to throw out ObamaCare in its entirety.
It was the states that created the federal government and delegated to it certain specific powers. It is the states that must reign in the federal government when it exceeds its limits as defined in the Constitution.
Small examples in Utah of this necessary push-back are 2012 legislative session SB 34 (Production and Sale of Food in Utah Revisions) and 2010 legislative session SB11 (Utah Firearms Freedom Act). Utah needs to do much more in this regard.
It is the duty of the states to nullify all unconstitutional federal laws and regulations.
An immediate special legislative is warranted to nullify ObamaCare and all other federal laws, policies, regulations, and agencies that violate the contractual conditions outlined in the US Constitution.
