Many Christians are reluctant to become involved in public affairs be cause politics is a "dirty business", but the same people are generally quite happy to go into business life, which is in its way just as "dirty". If the dubious practices and moral compromises of every walk of life were dissected and made known with the glare of publicity which shines on the activities of politicians, then those who like to think that they can keep their hands clean would have very few professions to choose from.
