Chris Matthews' Election Day lecture on the American political system perhaps lacked something in eloquence, but it possessed the merit of simple truth:
If you don’t vote you’re an idiot.... The haters all voted, they always vote.... And if you vote for one of these numbskull third or fourth party candidates like Gary Johnson or Jill Stein and say, oh I was so surprised at what happened — no you shouldn’t be, because idiots like you ... don’t know how the system works. You have two choices.
Nevertheless I would encourage libertarian idiots not to waste a vote on Mitt Romney. Johnson's your man.
