(HT:William C. Fisher: "This is as relevant today as it was almost 100 years ago.")
If Christians should vote their duty to God at the polls, they would carry every election, and do it with ease. They would elect every clean candidate in the United States, and defeat every soiled one. Their prodigious power would be quickly realized and recognized, and afterward there would be no unclean candidates upon any ticket, and graft would cease. No church organization can be found in the country that would elect men of foul character to be its shepherd, itstreasurer, and superintendent of its Sunday-school. It wouldbe revolted at the idea; it would consider such an election aninsult to God. Yet every Christian congregation in the country elects foul men to public office, while quite aware that this also is an open and deliberate insult to God, who can not approve and does not approve the placing of the liberties and the well-being of His children in the hands of infamous men. It is the Christian congregations that are responsible for the filling of our public offices with criminals, for the reason that they could prevent it if they chose to do it. They could prevent it without organizing a league, without framing a platform, without making any speeches or passing any resolutions -- in a word, without concert of any kind.
They could accomplish it by each individual resolving to vote for God at the polls -- that is to say, vote for the candidate whom God would approve. Can a man imagine such a thing as God being a Republican or a Democrat, and voting for a criminal or a blackguard merely because party loyalty required it? Then can we imagine that a man can improve upon God's attitude in this matter, and by help of professional politicians invent a better policy? God has no politics but cleanliness and honesty, and it is good enough for men.
… If the Christians of America could be persuaded to vote God and a clean ticket, it would bring about a moral revolution that would be incalculably beneficent. It would save the country -- a country whose Christians have betrayed it and are destroying it.
