Romney is confronted by an individual that requires medical marijuana and asks Romney if he would arrest him and his doctor for using it to treat his symptoms. Romney's indifference to the suffering is pretty amazing.
The same questioner poses a similar question to Ron Paul. Paul makes a great point. They won't be criminalizing alcohol even though it is far more destructive. Politicians drink alcohol. Watch Paul.
It's rather incredible that Paul, with such a sensible, and popular position, is a fringe candidate and Romney who must advocate unpopular views to please certain powerful elements, is the front runner.
