Different electoral systems affect voter representation by determining how votes translate into seats in a legislature. For example, proportional representation systems tend to produce more accurate reflections of public opinion, allowing smaller parties to gain seats and giving minority groups a voice. In contrast, majority systems may concentrate power in fewer hands, often marginalizing smaller parties and under-representing diverse viewpoints. This can lead to voter disenchantment and social division if significant groups feel their interests are overlooked. Ultimately, the choice of electoral system can either enhance or undermine the principles of democracy and effective governance.
