Why does President Obama keep quiet?

Potheads in the U.S. are doing their best to make legalization of marijuana look like a panacea. According to these potheads, legalization will solve states’ financial problems, and offer jobs, security and well-being – all claims that would serve well for a book titled “How to fool a nation – a manual for dummies”.In the meantime President Obama keeps quiet in good company with Eric Holder at the US Department of Justice. Why and for how long, one might wonder?
