Ron Paul wants to legalize heroin?

Ron Paul is the GOP's leading libertarian. His ideologically pure stands on heroin and other issues (e.g. prostitution) may cost him many conservative votes. He naively concluded that if heroin were legalized "nobody" would use it. His frankness will, IMHO, keep hm from getting the GOP nomination for Pres. This highlights the split between the GOP and its libertarian wing. Libertarian ideas frighten many on both the liberal left and conservative right. There is a libertarian political party, but it will never really take off. While I agree with many libertarian ideas, I am a "cautious" libertarian and feel legalizing heroin and cocaine are massive, risky public health experiments that are too risky.
