A politician (from Classical Greek πόλις, "polis") is a person active in party politics, or a person holding or seeking office in government. In democratic countries, politicians seek positions within a government through elections or appointment. In non-democratic countries, they employ other means of reaching power through appointment, bribery, revolutions and intrigues. Some politicians are experienced in the art or science of government. Politicians propose, support and create laws or policies that govern the land and, by extension, its people. Broadly speaking, a "politician" can be anyone who seeks to achieve political power in any bureaucratic institution.
Politicians are people who are politically active, especially in party politics. Positions range from local offices to executive, legislative, and judicial offices of regional and national governments. Some elected law enforcement officers, such as sheriffs, are considered politicians.
Politicians are known for their rhetoric, as in speeches or campaign advertisements. They are especially known for using common themes that allow them to develop their political positions in terms familiar to the voters. Politicians of necessity become expert users of the media. Politicians in the 19th century made heavy use of newspapers, magazines, and pamphlets, as well as posters. In the 20th century, they branched into radio and television, making television commercials the single most expensive part of an election campaign. In the 21st century, they have become increasingly involved with the social media based on the Internet and smart phones.
