It's not there and that means they don't have it - the states do. Obamacare is obviously unconstitutional as is 99% of what the feds do. The states need to grow a pair and scream about this.
Nowhere in the Constitution does it mention a federal interstate highway system, air traffic controls, a federal department to inspect food and drugs, the EPA, or a Department of Agriculture. Yet, we have all of this federal agencies.
Exactly! All of which are unconstitutional bullshit which the federal government had no business sticking their nose in. You just illustrated exactly why we are $17 trillion in debt and about to collapse like the old Soviet Union.
Perhaps you should read the Preamble of the Constitution.
"
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
See the part of the Preamble where it says "promote the general Welfare?" What could better promote the general welfare than health care for all the citizens of the US?
