Ron Paul shows Giuliani, McCain, and Romney how to talk about medical marijuana without sounding like a monster. Hint: tell everyone you care about sick people. Voters love that stuff.

Ron Paul, supposedly a fringe candidate, seems to understand formerly cherished conservative principles like "states rights" better than any other republican running.

The success of Paul's campaign is yet another demonstration that smart and compassionate positions on drug policy are neither exclusively liberal nor politically suicidal.
