California had MMJ since 1996, with Bush in power from 2000-2008. The heaviest crackdown to date has been by the betrayer Obama, a democrat.
Romney is MMJ hostile, but he is no king. Some of our governors would take exception to an attack on patients within the state. It would make the state leadership look weak, and hurt re-election. No, I don't see a Mormon future but a future of secular humanism. Romney would need to focus on the economy and budget. Social issues are not a priority right now for most people.
The national numbers are irrelevent. Obama will win, I think. But if not, Romney can't be much worse than Obama. Without having to win re-election, Obama can have cannabis rescheduled and only be better in his second term.
