Commerce Clause Equals Unlimited Government?

That’s why Obamacare isn’t just a threat to the private health care system. It strikes at the very foundation of our nation. In our earliest days, Chief Justice John Marshall warned that if Congress can exercise powers that are in practice unlimited, then “written constitutions are absurd attempts, on the part of the people, to limit a power in its own nature illimitable.” It is “a proposition too plain to be contested” that the Constitution cannot be used to justify an act that destroys the very limits on which constitutional government is founded, he wrote. The courts should move expeditiously to throw out the president’s unconstitutional power grab.
