One way through which parties can evolve is through their number as well as the different philosophies or ideas which they stand for or support. It is important to note that political parties are not static vehicles of change, but they respond to every stimulus within their environment of operation. Such responses are a result of the number of political parties which operate in one particular country. When there is only one political party in operation, there will be no competition for it to evolve. Hence party competition is one way through which positive growth can be realized in political parties.
Canada, the United States, Germany, Spain, and Italy have evolved their political systems with time. In these countries, parties are voted for by the people. Political parties begin by drawing manifestos that act as their agenda. It is then upon those officials who are nominated by the party to pursue these agendas. Further, party funding is an essential ingredient in facilitating party operations. Members of the party have the role of funding the political parties, which they through a membership fee, which is charged upon registration. However, the system practiced in the United States is quite unique. The initial plan was meant to cushion a political structure that had no party system. The candidate makes the sole decision on the party of choice in terms of funding and seeking registration.
In Germany, the multi-party system has evolved over a period of time with the limited number of parties involved in the country’s politics. There are only two parties at present. Italy is also embracing more than the one-party system in its political structure. The parliamentary system also ensures that the ideals of democracy are upheld. The development of multi-party systems in Eastern Europe has mainly been accelerated by external influence from countries that had already adopted multi-party politics. This led to the introduction of domestic pressure groups, which sought the establishment of multi-party politics. Moreover, calls by the international community to adopt modern political systems and structures acted as an impetus toward the introduction of multi-party.
