The problem is that if your in for a penny your in for a dollar. The way it works in our new society is that you will pay for it, get use to it they won.
While I personally advocate legalization of drugs and prostitution, I recognize that as a practical matter neither major party is going to make headway towards doing so (possible exception: marijuana). In any case it's not at the top (or even middle) of my agenda; my most important issues are fiscal responsibility and foreign policy. As such, I vote a straight Republican ticket.
Granted, I have to hold my nose while doing so at times.
