Why ObamaCare is unconstitutional

In fact, the Supreme Court in United States v. Lopez (1995) rejected a version of the commerce power so expansive that it would leave virtually no activities by individuals that Congress could not regulate. By requiring Americans to use their own money to purchase a particular good or service, Congress would be doing exactly what the court said it could not do.

Some have argued that Congress may pass any legislation that it believes will serve the “general welfare.” Those words appear in Article I of the Constitution, but they do not create a free-floating power for Congress simply to go forth and legislate well. Rather, the general welfare clause identifies the purpose for which Congress may spend money. The individual mandate tells Americans how they must spend the money Congress has not taken from them and has nothing to do with congressional spending.
