The Libertarians are more conservative on economics and freedom of the individual than the Republicans.Just look at the ludicrous scenarios of the Senate of late!
However, they are totally off base on defense of the country and other isolationist perspectives.
By the way NOBODY is taking a reality stand on illegal immigration! If the minutemen ran for Senate, they would have my vote!
Lots of freepers think libertarianism is a leftist philosophy...so do a lot of leftists, idiotically. Truth is that it's closer to the classical liberalism of our forefathers than most of what's out there today.
