Compare it to another issue for illustration: Do you believe it would be better policy for the government to ban marijuana commerce entirely, as is usually the case today, or to regulate it? Why or why not, and whom would benefit or be harmed either way?
I would say that drug regulation depends on how spread it is in the particular society. Banning commerce (outside medicinal proscription) of drugs that are not commonplace appears sometimes to be effective to prevent it from entering, while not effective when it comes to drugs that are already established.
I think this answer illustrates that it depends on the situation... A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!
