Run by Libertarians, Advocates for Self -Government also has a list of Libertarian celebrities, which I found rather interesting. I had assumed some of them were Republicans.
It also lists the differences between Liberals, Conservatives, Libertarians and Statists:
Right (Conservative) Conservatives tend to favor economic freedom, but frequently support laws to restrict personal behavior that violates "traditional values." They oppose excessive government control of business, while endorsing government action to defend morality and the traditional family structure. Conservatives usually support a strong military, oppose bureaucracy and high taxes, favor a free-market economy, and endorse strong law enforcement.
Left (Liberal) Liberals usually embrace freedom of choice in personal matters, but tend to support significant government control of the economy. They generally support a government-funded "safety net"to help the disadvantaged, and advocate strict regulation of business. Liberals tend to favor environmental regulations, defend civil liberties and free expression, support government action to promote equality, and tolerate diverse lifestyles.
Libertarian Libertarians support maximum liberty in both personal and economic matters. They advocate a much smaller government; one that is limited to protecting individuals from coercion and violence. Libertarians tend to embrace individual responsibility, oppose government bureaucracy and taxes, promote private charity,
tolerate diverse lifestyles, support the free market, and defend civil liberties.
Statist (Big Government) Statists want government to have a great deal of power over the economy and individual behavior. They frequently doubt whether economic liberty and individual freedom are practical options in today's world. Statists tend to distrust the free market, support high taxes and centralized planning of the economy, oppose diverse lifestyles, and question the importance of civil liberties.
