The electoral system used in Nigeria is primarily based on __________

The electoral system used in Nigeria is primarily based on the first-past-the-post system.
Under this system, each constituency in Nigeria is divided into electoral districts, and voters in each district elect a representative through a simple majority vote. The candidate who receives the highest number of votes (even if not a majority) is declared the winner and becomes the representative of that district.
This system is commonly known as "first-past-the-post" because the candidate who passes the winning post first by having the most votes is elected, irrespective of whether they have received an absolute majority or not.
The first-past-the-post system is straightforward and easy to understand. It allows voters to choose a representative based on the individual and their party affiliation. It also allows for a direct connection between the elected representative and the constituency, as each district has its own representative.
