Majority-rule voting is a decision-making process where the option receiving more than half of the votes is selected. It is widely used in democratic systems to ensure that the choice reflects the preference of the majority of participants.
The Median Voter Theorem posits that in a majority-rule voting system, the candidate or policy that aligns closest to the preferences of the median voter will win. This theorem assumes a unidimensional political spectrum and voter preferences that are single-peaked, highlighting the influence of centrism in democratic elections.
