Noted and highly influential individualist anarchists Lysander Spooner and Murray Rothbard weep at the 'logic' of the non-voting anarchist population...
Look folks, you will be oppressed by a president. His vision of morality will be imposed on you, whether you like it or not, regardless of your ideology. You might as well support someone who will try his darndest (with the limited extent of his power) to remove as much oppression and maximize as much individual liberty in your lives as possible.
Here's a hypothetical to illustrate my point. You're tied down. A criminal points a 44 magnum at you at point blank range and says...
"Choose. I am going to either shoot your hand off or shoot you square in the chest. If you do not choose, I am going to shoot you in the chest anyways."
Based on the circumstances surrounding this situation, there is no question that he will end up shooting you. Are you going to tell him, "Fine, shoot my hand off." - or will you instead tell him, "I will not choose, because either choice is advocating you do evil."? Or not choose simply because you don't like either of the choices available to you?
Do you realize how counter-productive if not completely self-destructive such mentality is?
At the very least, Ron Paul as president can end the wars and militarism in one fell swoop - as the President has ultimate control of military forces. He would also be a major facilitator that would be needed in passing certain legislation (and of course, repealing a lot of legislation) if more seats are gained in congress that support positions of liberty. He would have a highly visible position in which to speak on and talk about liberty and free markets for the world to see. Even just as a contender with limited time in the 2008 GOP Primary Republican debates - he sparked a libertarian movement and adoption of libertarian philosophy at a rate never before seen. Back in 2006, I was a ruthless neocon imperialist and a - get this - a Rudy Giuliani supporter. Not after the debates. You see, Ron Paul is a *very effective* 'gateway drug' to exposing people to the spectrum of libertarianism.
As for the idea some have that, "I just hope you all don't really believe Ron Paul will ever be President."...
That may very well be the case. But this is the best chance we've had since Barry Goldwater to really get a liberty-minded individual to actually be elected as president. We must recognize the self-fulfilling prophecy that we are creating if we say (as I am so often told), 'Don't vote for him, he won't become president anyways'.
I am not saying that voting is and should be the only tool we use to attempt to gain liberty and minimize the role of government in our lives. There is also agorism, civil disobedience, education (one on one, as well as to a group in real life and/or online in debates, discussions, et cetera), media infiltration ('Freedom Watch' and 'Stossel' come to mind) to more effectively inform the masses on libertarianism, and many others.
What I am saying is that we should not limit ourselves or forsake voting as one of the many tools available to us in the toolbox for advancing liberty. Whether that tool is merely to throw a wrench in the statist machine in order to slow or disrupt it's growth, or use it to marginally advance the cause for liberty in more specific ways - we must acknowledge it's legitimate role in the unfortunate reality of our situation.
