Bill Whalen knows a lot about California politics, and I won’t quibble with his predictions. Like him, I’m not especially swayed by the tax-revenue argument for legalizing marijuana. And I’ll add that he’s right that it’s not “practical” to confine legalization to personal harvesting. But that strikes me as an argument for a broader liberalization, not for refusing to take the first step. (It’s not as though it’s practical to enforce the current law.) Prop 19 may be headed for defeat. But if I were a California voter, I think I’d support it.
