I don't disagree with your perspective. It would certainly be a start. However, I do think it is necessary that any drug fight undertaken by a state be constrained by proper limits on prosecutorial power. And I do think it is appropriate that state laws on the issue be consistent, logical, and that punishments be commensurate with the harm.
Let's take, for example, the recent Federal restriction on student aid - if you have a misdemeanor pot possession conviction, you can't get student loans. But if you are a convicted rapist, you can. Or a convicted murderer. Or if you have been convicted of loan fraud. These penalties apply only to drug crimes. I'm sure presidio loves such laws, but they make no sense. Then again, it seems he loves all laws that restrict freedom.
