You and your wife should and will vote as you please, which is your right.
IMO, it would be too bad for the rest of us if the stated reason that anyone decides to vote no on Prop 19 is because the federal government is having a hissy fit.
It is clear the panic button has been hit (“Hey, this thing may actually win?!?”). Out trot the current/former drug czars and cadre of other political whores (thanks, Jerry, for helping me find the right word to describe you guys) to explain how they know better than us mush-minds, and they promise to keep arresting and ruining the lives of people for their own good (both meanings intended).
Since they believe most Americans have little capacity for or interest in critical thinking, they explain in the usual patronizing tone that decriminalization plays into the hands of Mexican Drug Cartels. I do not expect anyone in the federal government to understand basic supply/demand economics, so they may actually believe what spills out their pie holes. They would be loath to admit that their war on drugs plays into the hands of Mexican Drug Cartels.
Our local fish wrap (San Jose Mercury News) recently explained that an important reason to vote no on Prop 19 is because California would be the only state to decriminalize pot. Of course, out the other side of their ass they simultaneously explain that we should vote no on Prop 23 because California needs to set an example (“lead the way”) for other states on clean energy policy.
I do not expect critical thinking from the San Jose Mercury News (and they oblige me), but I see a great deal of it demonstrated in the original posts and comments on this blog.
