You just said anyone who has ever contributed to a presidential campaign in their life is a moron. I don't see how this can be interpreted any other way, no one pisses away $100 to the Libertarian candidate expecting he's really going to save over $100 in income tax or reduced regulations the next year...

I would say that giving money to a libertarian (or other) candidate is a very clear message that you favor their policies compared to the alternatives. Yes, $100 isn't going to move the needle but neither is your individual vote in the vast majority of cases.
