Voting and the neighbor

Todd Wilkens, host of Issues, Etc., has a provocative post on voting like a Christian.  He is applying to this work of the calling of citizenship what Luther taught is the purpose of all vocations:  To love and serve one’s neighbor.

Why does a Christian vote? A Christian doesn’t vote for the same reason the unbeliever votes.

A Christian doesn’t vote because it’s his right. That’s why the unbeliever votes. For the Christian, his own rights have nothing to do with it.

A Christian doesn’t vote to get his way. That’s also why the unbeliever votes. For the Christian, getting his way has nothing to do with it.

A Christian doesn’t vote to protect his own interests. For the Christian, his own interests have nothing to do with it.

A Christian votes to serve his neighbor —-period.

A Christian votes because he is called to do so by the needs of his neighbor. This means that a Christian will sometimes vote against his own rights, his own way and his own self-interest; but always in favor of his neighbor and his needs. At the ballot box, the neighbor comes first.

On election day, don’t vote like an unbeliever. Make you vote count …for your neighbor.

So what difference would this neighbor-centered ethic make?  Which, in your opinion, would be a better neighbor-centered vote, for Obama or for Romney?  Is there only one answer, or might vocation lead different people to different decisions?  If the latter, does that mean that God calls people to contrary actions?  How can that be?
