A method or prism to view contemporary political movements such as the tea party?  Utilitarianism vs Libertarianism

"Sandel introduces the libertarian conception of individual rights, according to which only a minimal state is justified. Libertarians argue that government should not have the power to enact laws that 1) protect people from themselves, such as seat belt laws, 2) impose some peoples moral values on society as a whole, or 3) redistribute income from the rich to the poor. Sandel explains the libertarian notion that redistributive taxation is akin to forced labor with references to Bill Gates and Michael Jordan." - you tube
