What does political parties do?

Parties contest elections. In most democracies, elections are fought mainly among the candidates put up by political parties. Parties select their candidates in different ways. In some countries, such as the USA, members and supporters of a party choose its candidates. Now more and more countries are following this method. In other countries like India, top party leaders choose candidates for contesting elections. Parties put forward different policies and programmes and the voters choose from them. Each of us may have different opinions and views on what policies are suitable for the society. But no government can handle such a large variety of views. In a democracy, a large number of similar opinions have to be grouped together to provide a direction in which policies can be formulated by the governments.
