Politicians

Politics is the process by which groups of people make decisions. Although the term is generally applied to behavior within civil governments, politics is observed in all human group interactions, including corporate, academic, and religious institutions.

Politics consists of "social relations involving authority or power" and refers to the regulation of a political unit, and to the methods and tactics used to formulate and apply policy.

Political science (also political studies) is the study of political behavior and examines the acquisition and application of power. Related areas of study include political philosophy, which seeks a rationale for politics and an ethic of public behavior, and public administration, which examines the practices of governance.
