We'd have a better chance with the Lollipop Guild. Best way for legalization is to just grow it and tell no one, flood the market with it, make it real accessible and cheap, cheap, cheap, drive those gangster assholes back into the cesspools where they belong and cause the gubmint to just say "fuck it". No polishitian is going to wade in on this, not if he wants a nice, yummy pension.
