Politics/Legends

Each planet has its own political system, most of which involve a House of Representitives to represent the planet's system. Each political system has its own constitution and law system, however it must comply with the Galactic constitution, unless it is brought to the attention of the Galactic Senate, where they may decide, usually by process of a vote, whether it is fit.

Most planets have either a King/Queen, such as on Naboo, or a President, or Chancellor, though the Chancellor of a planet's political system is still inferior to the Supreme Chancellor of the Republic. A King/Queen, President or Chancellor can either be chosen by election, or by way of inheritance. There is an equal number of planetary political systems run by inheritance as there is by election. Almost all planetary Representatives are chosen by election. Naboo is a planet with a well known Political System.

Behind the scenes
When Revenge of the Sith was released, George Lucas was criticised for using the film to promote a liberal agenda, but has responded that the prequel trilogy was originally conceived in the 1970s and influenced as much by Richard Nixon as George W. Bush.
