What is at the center of a reprensentative democracy

Majority Rule

Explanation:

In a representative democracy, the citizens elected the group of people that will get the government position. These elected people are tasked with the duty to "Represent the voters' interest" by passing the legislation that benefit their voters.

During the voting process, the representatives will promote themselves to the public through political campaigns. They will let the public know what type of plans they have for the social matters and Economic strategies.

Each citizens will have different opinion and tend to choose the Representatives that they believe will be beneficial for their own needs.

So, when the Voting number is accumulated, we can state that whoever wins and elected to be the Representatives is elected by 'Majority Rule' and trusted with the task to fight for the Majority of the people.
