Restricted franchise violates the idea of political equality. Political equality is the principle that all citizens should have equal political rights and opportunities. When the right to vote is restricted based on factors such as race, gender, wealth, or education, it violates political equality because it gives some individuals or groups greater political power than others. This can lead to a situation where some people's voices and interests are ignored, and the government may not be representative of the entire population. Therefore, a restricted franchise, where only certain individuals are allowed to vote, goes against the principle of political equality, which is a fundamental aspect of democratic societies.
