A politician is a person who has political power in the government of a state, a person active in party politics, or a person holding or seeking an elected office in government.
Politicians are people who are politically active, especially in party politics. Political positions range from local governments to state governments to federal governments to international governments. All government leaders are considered politicians.
In Japan's Public Offices Election Law and Political Funds Control Law, "candidates, prospective candidates, and those currently holding public office who are elected by public election" are collectively referred to as 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 smartphones.
Rumor has always played a major role in politics, with negative rumors about an opponent typically more effective than positive rumors about one's own side.
Once elected, the politician has to deal with government officers and government employees working for them. Historically, there has been a subtle conflict between the long-term goals of each side. In patronage-based systems, such as the United States in the 19th century, winning politicians replace the government officers and government employees not protected under the government services rules with their supporters. It was the "spoils system". Government job reform was initiated to eliminate the corruption of government jobs.

Gouverneur est un titre qui a désigné différentes fonctions suivant les pays et les périodes. En règle générale, le gouverneur est la personne qui détient le pouvoir exécutif civil ou militaire, ou les deux, d'une province, d'un État (dans le cas d'une fédération) ou d'une colonie. Il répond le plus souvent à une autorité supérieure, bien souvent le chef de l'État ou le gouvernement du pays pour lequel il agit. Dans un État fédéral, il gouverne au nom du pouvoir central s'il est nommé ou de manière autonome s'il est élu (cas par exemple des États des États-Unis).
Le Premier ministre est généralement le chef du gouvernement dans les régimes au pouvoir exécutif bicéphale. Dans certains régimes parlementaires, entre autres celui du Royaume-Uni, ou dans un régime semi-présidentiel, le Premier ministre et son gouvernement sont responsables devant le parlement. Le Premier ministre est généralement élu par le Parlement, éventuellement sur proposition du chef de l'État, ou bien nommé directement par le chef de l'État.
