Liberal means different things depending on context, country, etc.
Over here in France (although not as common a term as in the US) it is commonly associated with economic liberalism, ie part of right-wing ideology (small government, fewer taxes, etc).
In the US, it's more of a synonym of social liberalism, and is associated with left-wing ideology, progressivism.
