The founders on the enumerated powers

Every time a law is passed, whether that law is free health care, bailouts, or any other thing, and a person asks where Congress gets the authority to enact such a law, the response is almost always the "general welfare" clause, or the "interstate commerce" clause. Let's see what James Madison, one of our founding fathers, had to say about that

If Congress can employ money indefinitely to the general welfare, and are the sole and supreme judges of the general welfare, they may take the care of religion into their own hands; they may appoint teachers in every State, county and parish and pay them out of their public treasury; they may take into their own hands the education of children, establishing in like manner schools throughout the Union; they may assume the provision of the poor; they may undertake the regulation of all roads other than post-roads; in short, every thing, from the highest object of state legislation down to the most minute object of police, would be thrown under the power of Congress.... Were the power of Congress to be established in the latitude contended for, it would subvert the very foundations, and transmute the very nature of the limited Government established by the people of America.

What about the commerce clause?

The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite. The former will be exercised principally on external objects, as war, peace, negotiation and foreign commerce...no state be at liberty to impose duties on any goods, wares, or merchandise, imported, by land or by water, from any other state, but may altogether prohibit the importation from any state of any particular species or description of goods, wares, or merchandise, of which the importation is at the same time prohibited from all other places whatsoever.

Hmmm. Looks like Federal Government control is not what the FFs meant when they wrote the commerce and general welfare clauses.
