Answer: Voting is the most important duty because as seen time and time again in history, your president/leader matters. If you don't vote, you might not be able to help the best candidate win. You could end up having a tyrant in a position of power. A piece of evidence that supports this is how King George III acted. They were a tyrant that taxed the colonists in American heavily and denied any attempts to amend the situation. We're lucky to be able to vote now so why would you waste that opportunity? Voting is one of the most vital duties you have.
