Once in a while I come across an op-ed filled with so many errors, misstatements, and plainly weak claims that the mere number of those becomes far more interesting than the argument of the op-ed itself. A case in point is today's Wall Street Journal op-ed by Fox News Channel senior judicial analyst Andrew P. Napolitano, which argues that President Obama's health care proposals are unconstitutional because they exceed the commerce clause power. Here's an excerpt; how many errors, misstatements, and plainly weak claims can you count?

  The Supreme Court finally came to its senses when it invalidated a congressional ban on illegal guns within 1,000 feet of public schools. In United States v. Lopez (1995), the Court ruled that the Commerce Clause may only be used by Congress to regulate human activity that is truly commercial at its core and that has not traditionally been regulated by the states. The movement of illegal guns from one state to another, the Court ruled, was criminal and not commercial at its core, and school safety has historically been a state function.
  Applying these principles to President Barack Obama's health-care proposal, it's clear that his plan is unconstitutional at its core. The practice of medicine consists of the delivery of intimate services to the human body. In almost all instances, the delivery of medical services occurs in one place and does not move across interstate lines. One goes to a physician not to engage in commercial activity, as the Framers of the Constitution understood, but to improve one's health. And the practice of medicine, much like public school safety, has been regulated by states for the past century.

  There are also errors by omission, like the curious decision to ignore Gonzales v. Raich, but I think it's only sporting to stick to claims actually made.
