"The only possible argument for [believing the federal government lacks constitutional authority to ban drugs] would involve a sweeping expansion of the fictitious 'right to privacy'—a whole-cloth invention of the Warren Court that conservatives (and originalists) generally hate."
Really? That's the "only possible" argument? What about the fact that banning drugs is not one of the enumerated powers given to Congress in Art. I, Sec. 8? What constitutional authority does Medved think justifies the drug war? The current ridiculous interpretation of the Commerce Clause? The same one that's been incorrectly used to justify Obamacare and the vast expansion of federal power over the last 100 years?
Fortunately, judging from the comments such as those below, people aren't buying this BS. Look at the thumbs up vs. down. That's a good sign.
