I always vote Libertarian even though I disagree with some of their positions, mainly as to the correct role / function of government.
While my main tenet is "leave me the hell alone and let me do what I want" I realize that there are always going to be people who need to be held in check, lest their nefarious ways interfere with the happiness of others.
Government then is a necessary evil, to both protect us and to help facilitate commerce.
I consider myself fiscally and militarily conservative and more open-minded on social issues.
I most certainly don't consider myself a typical Portland liberal, although I choose to live in a progressive part of the country.
