Any argument pro or against libertarianism is a philosophical one, not really a factual one, since accurate studies have not been done over a long period time. And since libertarianism is split into different factions, and none agree on the proper amount of government coersion necessary, you might as well just look at Democrat and Conservative factions which support your own view of how much government is necessary. Not all democrats want big government. A person can be libertarian democrat or libertarian conservative. I agree with the basic principle that anything should be allowed as long as it does not infringe on anyone else's individual rights. But Libertarians can not agree on what restricts a person's individual rights. I think the good democrats (the ones who don't want outright socialism and equality) are on the right track about what restricts a person's individual rights. There are also good republicans who are against mixing church and state. So there's good in all 3 of those parties I mentioned. Its not a matter of one party winning over the others, but of the American people choosing their leaders wisely from the spectrum of candidates. Bush was a way wrong choice in this regard, and was on the team of take as much as you can get, rather than laissez faire w/ government safeguards.
