I vote pretty much solidly libertarian at all times. I'll check the polls leading into any major statewide elections and see if its within the margin of error and if I think one of the lesser-evils can or will address in any competent manner the most important issues in my view (pension reform here in California), than I may vote for him/her if the difference in candidates is large enough on the high-priority issues. As for federal offices, I have the unfortunate burden of living in Henry Waxman's district and since he is guaranteed to never lose thanks to our gerrymandered districts here, I don't consider voting my true libertarian belief to be a wasted vote. POTUS elections, California is a guaranteed Dem seat too, so again, I'm not wasting my vote. Besides, is a vote not more important when you represent 0.00001 of a candidate's overall vote total as opposed to 0.000000000001?
