Concept of Two-Party System:

A two-party system is always dominated by two main parties in the political landscape of a country. This is so because the two-party system creates a structure that presents them with a large pool of followers as a result of their experiences, popularity, reputation and calibre of members. In fact, these two parties are so popular to an extent that some of the other political parties become obscure or unknown by majority of the citizens. For this reason, the two dominant parties will always collect the majority of votes by the electorate; and typically, one eventually emerges as the winner of a presidential election.

Please read more on the Two Party System and its Characteristics here.

Note: The two-party system also dominates the legislature and state elections.

Please read on the Legislature as an Arm of Government here.

From 1998 to this moment (2020), two political parties have dominated the Nigerian politics. These are:

Democracy is a form of government where the power of choosing a leader is vested on the people. It represents a government of the people, by the people and for the people.

According to Abrahim Lincoln,

Democracy means government of the people, by the people and for the people.

In democracy, the citizens have the rights to vote and be voted for. The citizens are mandated to choose their preferred candidate by voting for them through their political party. In fact, this voting process is considered as one of the civic responsibility of every citizen.

Please read on the fundamental Human Rights here.

NOTE: No one is above the rule of law in the democratic system. If the election outcome does not reflect the mandate of the people, a court of competent jurisdiction can nullify such election.

Democracy is practiced in countries like Nigeria, United States of America, India and South Africa.
