I agree, this is a good read. I also agree that there is no state right to nullification in the sense that a state can invalidate a federal statute. It can, however, refuse to enforce it. That’s no small thing as the Federal government usually relies on the states to do its work. That’s the reason in my view why the CO and WA marijuana laws are being tolerated: the Feds don’t have the ability to enforce their laws anyway. So they’re posturing and calling it an experiment when in reality there isn’t much they can do about it anyway.
Something to keep in mind.
A pity that we have two states willing to refuse to enforce the federal drug laws, but it has never occurred to any state to refuse to obey Roe v. Wade, Doe v. Bolton, or Casey vs. Planned Parenthood.
