I liken voting to granting consent in the following way:
Say a friend comes to me and says "Hey, I challenge you to a game of chess". I have two options, I can play the game or refuse to play it. If I refuse to play the game, my friend cannot legitimately and honestly go around saying "I beat Jon at chess!" because I never actually played the game and I therefore do not have to consent to his "victory".
If I choose to play the game with my friend, and my friend objectively beats me, then it is honest and legitimate to say that he beat me at chess. Voting is a game we can play (a rigged game) and by engaging in it we consent to the outcome of the game even if we lose. Theodore J. Lowi has noted how voting is playing the game. He argues that people who in engage in the political process are people who are playing the game and people “who play the game must accept the outcome. Those who participate in politics are similarly committed, even if they are consistently on the losing side.”
So voting is consent and I do not consent to be ruled therefore I will to play the game and beg the slave masters for slightly looser chains.
