They don't because like Marxism, it is a ivory tower sort of ideology that can only work because it's adherents are protected by the very system they decry from ever having to actually live up to their self proclaimed dogmas.
that made no sense at all. Libertarians don’t win because they present an unpopular vision of politics. How can you possibly be elected if you are saying that you aren’t going to give people things? Liberty doesn’t sell. Many Republicans shout about limited government, but can’t spit out a coherent sentence about why it should be limited. It’s really pretty simple on one level: the government should do those things it can do more efficiently than the market, and leave everything else alone. The parallel to Marxism doesn’t exist.
Sorry but I disagree. We have a two party system and lately it is far left and center right. Real conservative candidates don’t get elected at the national level either. Reagan was the last one and that had a lot to do with Jimmuh Carter being such a moron.
