Perhaps things will change, but right now nearly every political party organization beyond the Democrat and Republicans are run like disjointed cluster****s that make the political systems of third world banana republics look fair and organized by comparison. How much respect can one have for the Libertarian Party (not libertarian principles, but the Party) when they allow ex-Republican Bob Barr to walk into their convention and steal the Party's nomination from candidates who actually, ahem, campaigned for the nomination and participated in the primary process? And who was Barr's running mate? Wayne Alan Root, who up until the year before was a Republican. And really, how effective can the Libertarian Party ever be when the bulk of its membership eschew many of the necessary evils needed to effectively run a national party? It's akin to handing out a schedule of events at a three day Anarchist convention. If you want politicians to best represent your beliefs, at this time, far and away the best way to accomplish that is to work within either of the two major parties.
Lastly, the poll that started this thread is a poll put together by Libertarians. Is it any shock that most people are getting "results" that indicate a libertarian tilt? Here's my equally scientific (i.e. not at all) and equally meaningless poll:
Do you like breathing air that is untaxed? A M D
Do you think the US should be capable of defending itself? A M D
Parents are better suited than govt. to raise their children? A M D
If you answered A to two or more questions, you're a Conservative. Now if I can just work a link into my poll so that you can contribute money to me like the Libertarians did with their poll.
