The principle of one person, one vote ensures that each citizen's vote carries equal weight in democratic elections. This principle is fundamental to maintaining a fair and equitable electoral process, meaning that no individual or group can exert disproportionate influence over the outcome. It reinforces the legitimacy of democratic governance by promoting representational equality and preventing discrimination based on socioeconomic status, race, or other factors. By ensuring that every vote counts equally, democracies aim to reflect the will of the majority while safeguarding the rights of minorities.
