Not all Christians vote. I do. For me it’s one of those privileges I’ve been given that I don’t want to take for granted. I’m skeptical about what actual goods state politics can realize. I doubt, for instance, that our governing authorities can make us better people. They can’t do much to make us more patient, more loving, more honest or more courageous. I vote, though, because it’s a modicum of power that’s been given to me and I want to use it to help our communities be more just. Not everyone has that opportunity.
There are two passages that frame the possibilities of governments biblically. One in Romans 13, where Paul describes governing authorities as God’s servants. They keep chaos in check by preserving a basic civil order. For that reason they deserve our support. 
Then there is Revelation 13, where governing authorities are depicted as a diabolical beast. The beast is worshiped because of its immense power and its seeming invincibility. For that reason they deserve our skepticism.
I vote, but I don’t think that’s the most ‘political’ thing I do. This evening I meet with the committee that plans our congregation’s worship life. It will be a political meeting. We will talk about allegiance and sovereignty. We will talk about how to cultivate certain virtues and ways of being. We will talk about economics and global alliances. We will do all that without mentioning a national government. It will be political, but it will have virtually nothing to do with a state. My point is not that state politics don’t matter—of course they do. My point is simply that Christians always hold more than one form of citizenship.
