Undervoting is defined as the practice of leaving some offices or ballot issues blank when voting. It is an important form of political expression as it allows citizens to express their dissatisfaction with the candidates or issues presented. Undervoting is especially important in the US because of its two-party system, which can limit the choices of citizens. This form of protest voting can help to send a message to the political establishment that change is needed. For example, if a large number of voters undervote in a local election, it could indicate that more independent candidates should be included in future elections to give voters more choices. Undervoting can also be used in primary elections to make a statement about the current two-party system and its entrenched interests. In this way, it is a powerful form of protest that can help to shape the political landscape.
