That's the biggest threat to the Liberatarian Party's viability right now. By their very stance on issues, they end up being for legalized drugs, lack of control on things, etc. It's the philosophy that drives them. It's also what seems to be driving much of their membership.

Probably the best thing they could do is to come up with a series of achievable short, medium, and long term goals and go from there. It'll likely cost them membership in the short term, but the members that hop onto the bandwagon later will be less loony and more likely to be able to create actual change.
