Please give me a break. That's a favorite leftist argument. Conservatives shouldn't stoop to it.
In spite of what the left says, the federal government has limited authority. The commerce clause was intended to address two problems. One was that some states would not allow the goods of another state to pass through their borders. The other was that some states had a tarriff on goods coming into their borders from another state. That's all the commerce clause was intended to address. And that's all the federal government can legitimately address with the commerce clause. A fact that the federal government pretty much recognized up until the 1930's. (There were exceptions, but nothing in a big way.)
