The principle of "one person, one vote" ensures that each citizen's vote carries equal weight in the electoral process. This concept is fundamental to a democratic system, emphasizing equality and fair representation in governing. It aims to eliminate practices that dilute the voting power of certain populations, such as gerrymandering and voting restrictions. Upholding this principle is vital for building public trust in elections and fostering civic engagement, as every citizen has a say in shaping government policies.
