A libertarian is a mix between a conservative and a liberal that is, for a change, not a hypocrite. Conservatives believe in social control, but economic freedom (a seeming contradiction) while liberals believe in the opposite; social freedom but economic control (another contradiction...why believe in partial freedom?). A libertarian, as the name implies, believes in freedom of both. That is, freedom to choose how to live your life (with or without religion, gay or straight, whatever) and a freedom to spend or save your money how you wish without the government taking it and re-appropriating it. They're conservative economically, and liberal socially.
