I don't vote. I am not apathetic, and I do care what happens in our world. But it would be very wrong for me to participate in the political process. A few years ago, I ran across an essay titled " Whether Choosing Red or Blue, Politics is Love of Mammon" by MIchael Degan. Mr. Degan perfectly summarizes my feelings about voting (emphasis added by me):

Despite any policy differences one could cite between the two major American political parties, the two parties are really more similar than they are distinct.

While it's true that Republicans and Democrats are polar opposites on some issues, neither party is really interested in reform or fundamental change. In fact, they work toward just the opposite. It is the nature of a political party to be concerned primarily -- perhaps solely -- with achieving and maintaining power. And though many American politicians trip over each other to brandish their Christian credentials, they have everything to lose from a true Christian ethos that denies the self, loves the enemy, and prefers the poor to the powerful.

The claims of some politicians notwithstanding, genuine Christian values of love, humility, and service are generally tossed aside when one steps into the political arena, whether to cast a vote or to receive it.

Democrat and Republican are two sides of the same coin -- a coin that Jesus called "mammon." And this is the choice we must make. Not between Democrat and Republican but between the alternatives that Jesus offers: God and mammon. "No one can serve two masters," Jesus reminds us (Matt. 6:24). We must choose.

I have come to recognize that when I vote, I am staking a claim to a piece of the mammon. And no matter what kind of world I think I'm voting for, when I engage in politics, I am ultimately working for what is in my own self interest. In order to vote, I must decide who my enemy is. And I must work for my enemy's defeat. How can I love my enemy when I do that? I have not found a way to vote and to love my enemy at once. Nor have I found a way to respond with love to my enemy's attacks and still stay in the contest. Political operatives use the language of hate toward opponents because it works. As a disciple of Jesus, I choose to speak that language no longer.

What does God really want from us in the end? Has God taken sides in the prominent political issues of our time? Is God rooting for us to make abortion illegal, to end the war, to wipe out poverty, to prevent gays from marrying? Does God need our political machinery to establish the heavenly kingdom on earth?

I have discerned that God does not operate that way. I believe that God is watching us most closely when we stand face-to-face with those who disagree, oppose, or resent us. How do we react? With love or with hate? In God's way or in the world's way?

I reject voting not because there is anything intrinsically wrong with it, but because of who I become in order to win. When I join in that contest, I can't help but succumb to the hatred.

Christians are called to proclaim the kingdom of God, not necessarily to create it. Creating is God's divine work. When we try to create the kingdom, we undertake a self-serving and vain exercise in which we choose friendship with the world, and by so doing choose "enmity with God" (Jas. 4:4)

Edited to add: There are many other reasons to argue against voting that have nothing to do with faith. This just happens to be my primary reason for opposing the process.
