Voting is your right. It sounds like a cliché, but it’s the most basic reason to vote. As a citizen, voting is your way of getting a say in the issues that your country faces and how to tackle them. Voting in your primary or caucus gives you the opportunity to choose the candidate who best represents your ideology and to do your part to get him or her on the ballot this November.
