Unlike the rest of the world, in America liberal and right-wing are opposites.
Yeah, I've never been able to figure it out either.
Liberalism is a right-wing ideology. Socialism is a left-wing ideology. When most people in the USA use the term "liberal" they actually mean permissive.
The Economist is an example of a largely classical liberal type of ideology. Modern day lefties have kept the concept of personal freedom but feel that the economic liberalism just translates into freedom for capitalists and subservience for everyone else.
As a result, most of the people classified as left-wing in the USA are liberal in terms of social attitudes, but not in an economic sense. They tend to be more socialistic, i.e. free/cheaper healthcare, education, more labour market and environmental regulation, etc, etc. This is largely the territory of the democratic party.
The types of people called conservatives in the USA have abandoned the socail liberalism, but not the economic liberalism. These people are for less tax, less government (but not when it comes to legislating morality), less regulation, etc, etc. This political ground most closely approximates that occupied by the Republican party.
The ideology which is the closest heir apparent to classical liberalism is modern day libertarianism. This is classified as a right-wing ideology. Naziism is a right-wing ideology. Communism/socialism is a left-wing ideology. Environmentalism and Feminism can be both left and right depending on the brand, but in practice they almost always fall into the left-wing category.
