It probably isn't. In the John Adams versus Thomas Jefferson election of 1800, then-President Adams' camp called Jefferson an atheist, a libertine, and a coward; they stumped with the claim that the election offered a choice between "God and a religious president, or Jefferson and no God!" The rumor was that Jefferson would gather and burn all the Bibles upon his second inauguration.
In response, then-Vice President Jefferson — it is the only time in U.S. history a sitting president and vice president ran against each other — countered in kind. His surrogates blasted Adams for his "hideous hermaphroditical character, which has neither the force and firmness of a man nor the gentleness and sensibility of a woman." Once friends, the two became such again in post-election days.
More examples can be given, but this illustrates that mud-slinging and vitriol are anything but novel in political campaigns. And the politicians may have learned it from the clergy in the American colonies. Some of the anti-Catholic and anti-Semitic language that rang from pulpits went far beyond "insensitive." It was crude, inflammatory, and wicked. "Whore of Babylon," "Christ-killers," and "Anti-Christ" — these are some of the many epithets used from pulpits to poison minds and prejudice hearts. The Ku Klux Klan had roots in those pulpits.
So what's the point here? It certainly isn't to minimize or excuse the blood sport that American political campaigns has turned into. It is simply to put what is happening now into historical perspective. It is also to say that politics isn't the only sphere of life where the verbal bombast has become reckless and injurious.
Here is a worthy goal for all of us to embrace:
Don't use foul or abusive language. Let everything you say be good and helpful, so that your words will be an encouragement to those who hear them (Ephesians 4:29 NLT).
