The Commerce Clause that Robert Gibbs says President Obama will use to claim that the federal government does have this power is no more difficult to understand than the words that protect our private property. It says: "The Congress shall have power ... To regulate commerce with foreign nations, and among the several states, and with the Indian tribes."
If you live in California and engage in a transaction with someone in Mexico, you are engaging in "commerce with foreign nations," and the federal government can regulate that transaction. It cannot force you to buy breakfast in a restaurant on Tuesdays. But if a restaurant you freely patronize buys grapefruits in Mexico, it can regulate that grapefruit transaction.
Similarly, if you live in Ohio and engage in a transaction with someone in Florida, you are engaging in commerce "among the several states." The federal government cannot force you to buy oranges once a week, but if a grocer you freely shop with buys oranges from a farmer in Florida, it can regulate that orange transaction.
Finally, if you engage in commerce "with the Indian tribes," the federal government can regulate that, too.
Over the years, liberals seeking to increase government control over our lives have tried to expand the meaning of commerce "among the several states" far beyond what the Framers understood it to mean. The most far-flung interpretation came in the 1942 case of Wickard v. Filburn. Here, the Supreme Court ruled that the federal government could use its power to regulate commerce "among the several states" to regulate the amount of wheat an Ohio farmer grew on his own land even though he never sold or traded that wheat but used it only for his own consumption on his own property.
It did take a whole team of lawyers to come up with this notion. But those lawyers -- serving as Supreme Court justices -- were not trying to understand the Constitution, they were trying to change it without going through the amendment process prescribed by the Constitution itself.
According to the Congressional Budget Office, until President Obama signed this health care bill, the federal government had never before ordered Americans to buy any good or service. The reason was simple: Until now, no president or Congress dared to exceed their constitutional authority in this way.
In November, I asked Sen. Orrin Hatch, the senior Republican on the Senate Judiciary Committee, about the constitutionality of the health care bill's individual mandate. "If that is held constitutional -- for them to be able to tell us we have to purchase health insurance -- then there is literally nothing that the federal government can't force us to do," he said. "Nothing."
Hatch is not given to hyperbole. He spoke truth. Forcing Americans to buy a product they do not want is a tyrannical act beyond the constitutional authority of the president and Congress. It must be repealed.
