More legal marijuana means more dumbass Obama voters. All the narcotics out there (illegal drugs) is part of the reason Obama and the Democrats have the upper hand.
With respect, I can right now off the top of my head, think of at least three middle-aged lifelong recreational pot smokers with whom I have often discussed politics over the years, who are at least as Republican/conservative anti-liberal anti-Obama as we are, you and I.
With respect ... vote fraud is the PRIMARY reason Obama and Democrats have the upper hand. In my long experience with recreational pot smokers as well as recreational boozers, about EXACTLY the same proportion are liberal as are conservative. The choice of "high" has zero to do with their politics.
It is counterproductive to assume otherwise.
