Nearly every day we pick up the daily paper and read of the moral terpitude infecting our society. When seeking an answer to what has gone so obviously wrong, many look to the state of politics in our society.
Politics by nature are staffed by a transitory group of people that mostly reflect the society it represents. These people are entrusted by the people they represent to be stewards of the common good and maintenance of the agreed upon government functions.
Much like society at large, there are good and bad stewards, therefore at no point are they charged with providing the nations moral guidance.
