The job of a Citizen is to keep his mouth open. We do that by voting. To refuse to vote is not a protest against the system, it's surrendering.
Our Founding Fathers designed our system to encourage contimplation. The Citizens choose the direction of our government by electing representatives to office. Once set, that direction is hard to change for the next several years. Ideally, before we step into the voting booth, we should spend some time to study the candidates. Both the incumbent and challenger deserve our due dilligence before we choose one over the other.
Don't go with the person who has the best soundbites. Go with the one whose values and ideals best align with yours. If you don't know how to decide, I have a suggestion for you.
