Cowen's response to my last post:
When it comes to marijuana legalization, I believe that the "anti-" forces will muster as many parental votes as they need to, to defeat it when they need to. The elasticity of supply is nearly infinite at relevant margins. Legalization may appear "close" for a long time, but in equilibrium it will not spread very far. The "no" votes will pop up as needed.
McArdle thinks Cowen might have a point:
I'm not saying this happens to every single person who has a kid. But in my experience, as the kids approach the teenage years, a lot of parents do suddenly realize they aren't that interested in legal marijuana any more, and also, that totally unjust 21-year-old drinking age is probably a very good idea. ... Maybe we have reached the high-water mark of this sort of personal liberty. As the baby boomers age, they will be less interested in directly exercising their right to smoke pot, which means that even if they still support legalization, they will be less motivated on the issue. Meanwhile, there will be more people in the electorate with young adult children who they worry about--and fewer young adult children.
