Voting is the holy sacrament of politics and it is greatly frowned upon by the state, media, academia etc if you decide not to participate.
It disturbs politicians and the politically connected that some people do not subscribe to the notion that politicians should be supreme rulers -this weakens the powers at be and undermines and demystifies politicians and their authority.
These are the ideas politicians and their friends fear and work hard at dismissing. Imagine what a scare for the politician if no one showed up election day. Politicians would lose the affirmation of somehow being superior along with the authority to tell us what to do and spend our money!
