Majority rule is a fundamental principle in democratic elections where decisions are made based on the preferences of more than half of the voters. This system functions by tallying votes and declaring the candidate or proposal with the highest support as the winner. While majority rule promotes effective decision-making, it can lead to issues like tyranny of the majority, where the rights and interests of minority groups may be overlooked. As a result, many democratic systems incorporate safeguards, such as constitutional protections, to ensure that minority voices are respected.
