I've been looking into Libertarianism myself out of pure disgust with DC antics over the past 15 years or so. I don't agree with their entire platform, but I agree with more of it than I disagree with. Overall, I think a smaller, more streamlined .gov would be a more honest .gov based on sheer statistical probability.
Besides, the "big two" could use some real competition. They spend more time looking at one another's aisle than they do looking at the country anyway. Screw em. If I throw my vote away doing what I think is right, then I didn't throw it away.
