What does "politics" mean?

Politics: The management of a political party; the conduct and contests of parties with reference to political measures or the administration of public affairs; the advancement of candidates to office; in a bad sense, artful or dishonest management to secure the success of political candidates or parties; political trickery. When we say that two men are talking politics, we often mean that they are wrangling about some mere party question. F. W. Robertson.
