No, but there is bureaucratic inertia.
Dumbass, was well, dumbass. Ashcroft and Gonzales? didn't seem very good at their job. Since 2009, the industry grew a lot. Perhaps not in Cali, but def. in Colorado, Montana, New Mexico, and in other Western States. At least in Montana, its the conservatives who called on the Feds, and its the conservatives who have issues with the growing acceptance. Short of incompetence, I really don't see a conservative having a better position on this. I think I'd like incompetence in the DEA, but the AG?
I disagree with the actions, I just don't hate or blame Obama for the current state of affairs like you do. What bothers me more about Obamas policies relate to "national security" and our presence in Afghanistan. There, Obama has actual authority.
