The Commerce Clause, Taxing, and the General Welfare

I have in my hot little hands a debate published in the Pennsylvania University Law Review about the Individual Mandate.  No less, the side that argues that te individual mandate is an unlawful power grab is written by the very same David Rivkin and Lee Casey who are arguing the plaintiff's case in Florida et al v. US DHHS: A Healthy Debate. The debate took place before final passage of the PPACA, so there is some uncertainty in the exact language at play.

Rivkin and Casey start out where I would in the Commerce Clause debate, noting that the Supreme Court has held that Congress has the power to pass laws to regulate "activities, [which] taken in the aggregate, substantially affect interstate commerce." Gonzales v. Raich, 545 U.S. 1,22 (2005). This standard was first applied in defense of a law which prevented a farmer from growing, but not selling wheat in Wickard v. Filburn, 317 U.S. 111 (1942).  Because the hoarding of wheat would drive prices down if every farmer did it, Congress could regulate the practice.
