What is Two-party system?
There are several states in the world, where politics is dominated by two [[Political party|parties]]. This is known as '''two-party system.''' According to [[Giovanni Sartori]], the following is true for such as system: # Each of the two parties is able to reach an absolute majority in parliament # When there are [[Election|elections]], usually one of the two parties wins an absolute majority # The party that is elected wants to rule alone # There's a large probability that with elections, the ruling party will change over time The [[Median voter theorem]] describes such a system: While at first the parties have programmes that are very different from each other, over time, they will get closer. Hotelling's law also describes this in [[game theory]]. Note that in such systems, there may also be other parties, bur these rarely have enough influence to win majorities in elections. Two Examples of countries that have a two party system are the [[United Kingdom]], and the [[United States]]. == Related pages == * [[Multi-party system]] - A system where there are many parties, Sometimes, several parties work together in government. * [[One-party state]] - There's only one party, but sometimes people can choose from different candidates of that party.
