This feeling of belonging is usually achieved through indoctrination, a process where citizens are instructed in the fundamental principles of any system of belief. Another pro of a one-party state is that all the decision making is left in the hands of one person or an elite group of people requiring very little or no input from the country's citizens which again can be looked at as cost saving and leaves little room for coalitions within a party system of two or more. .
Of course along with the positive there are negative aspects to a one-party system. The Government is not limited as there needs to be no consent by the people. One or an elite group, leaving no decision making in the hands of citizens, holds the control of power. The civil liberties and rights of the people are not guaranteed in practice and because of this Government does not always follow rule of law and unfortunately in a one-party system force or threat of force are used frequently to keep peace. The political way of life of the one-party system is one of state control and public obedience and there is no possibility for competition among political parties, as elections do not offer a choice. .
The definition of a two-party system is a party system in which there are two credible contenders for power and either is capable of winning any election. An example of a country with a two-party system is the United States where the political contenders are either democratic or republican. Again in any political system there are pros and cons. The pros in a two-party system include the fact that there are only two parties to choose from. Though this limits the competition, there will still be a degree of competition, as each of the party's candidates wants the electorate vote. Because there are only the two parties, there will always be a majority win. This eliminates coalition governments because there is only the one choice and the party with the most votes forms the Government.
