I think you will surprisingly find most liberals and conservatives united on this issue. Prohibition has failed. Prohibitions always fails.

The best way to get people not to do something is to attach a social stigma to it. Passing laws against it can often have the opposite effect.

The biggest hurdle to getting this overturned is not the politicians. It is the entrenched bureaucracy that is dependent on the "War on Drugs" for funding. The DEA and local police agencies will fight this tooth and nail as they get significant funding (and the ability to buy fun toys like armored vehicles and fully-automatic weapons) to fight this "war".
